Major New Certification by ISA
• “High Stakes” certification used for hiring, advancement,
and contracting decisions
• Setting the standard for automation knowledge
• Worldwide credibility
• Not just one more credential, THE credential for
professional level automation knowledge
Market Studies Show Strong Interest in
Automation Certification
• 77% of the respondents believed certification would enhance
recognition and respect for individuals working in this field
• 67% of the respondents reported that certification in this field would
be valuable to their organization.
• 64% of the employer respondents agreed that
salary/remuneration/benefits should increase for certified industrial
automation professionals.
• 77% of respondents indicated that they would encourage eligible
employees to seek certification in this field if it is offered by ISA.
Employer respondents cited
the following benefits for CAP:
• -Increased quality
• -Safety
• -Standardization
• -Professional recognition
• -Additional means of evaluating potential job candidates
• -Help to weed out amateurs posing as automation
specialists
Who Is ISA?
• A leading, global, nonprofit organization
• Setting the standard for automation
• 30,000 worldwide members
• Develops standards
• Certifies industry professionals
• Provides education and training
• Publishes books and technical articles
• Hosts a number of conferences including the largest conference and
exhibition for automation professionals in North America.
Like certifications in many other fields,
CAP adoption driven by:
• Individual automation professionals
who want to distinguish their automation knowledge
• Companies with professional automation employees
who want to advance the education of their employees
• Companies providing automation services
who want to distinguish themselves in the market
• Users of automation services
who want to improve the quality of services they purchase
…rather than by any legal requirement
CAP Benefits Individual
Automation Professionals
• Enhances professional credibility
– Travel from job to job and provide immediate proof of ability.
– Younger professionals increase their recognition and credibility
– Mid-range professionals validate and document their range of knowledge
– Those nearing retirement enhance their future marketability
• Enhances self image
• Improves career opportunities -
promotion, pay increases, job portability
• Encourages life long learning and professional development
Individuals also tend to be early adopters of a new certification…
and many have achieved CAP status have done so to enhance their
own credibility
CAP Benefits Employers of
Automation Professionals
• Develops a better trained workforce
– Provides documented evidence that employees are qualified to do their
job. Such documentation is a requirement of the ISO 9001 standard.
• Incentive for employees to remain current
• Promotes safe practices
• Qualification tool for hiring and advancement decisions
• Enhances company image with internal or external
customers
Employers tend to be early adopters of a new certification…
and many employers are encouraging their key employees to
become certified
CAP Benefits Companies Providing
Automation Services
• Provider companies can distinguish themselves in the
market by advertising that their employees are certified
• Many users of automation technician services require
CCST certification,
and providers who can supply CCSTs have an advantage –
the same thing will happen with CAP
• Qualified automation professionals doing the work results
in fewer call-backs, less rework, and higher profits
CAP Benefits Companies Contracting
for Automation Services
• When outside companies do your automation design
how do you know that…
– The people doing the work on your projects are competent?
– Your safety critical systems are designed in the best way and to
the latest standards?
– Your plant will get the greatest advantage from the latest
standards on batch recipe management, data integration,
fieldbus, wireless, and other areas?
• If the people doing your work have a CAP credential…
– They have demonstrated competence
– Their knowledge of automation is well above average
– They are much more likely to know the latest standards
– Continuing education requirements keep knowledge up-to-date
More Competent Automation Professionals
Develop Automation Systems that…
• Are less expensive
• Operate more efficiently
• Are easier for operators to work with
• Are easier to maintain
• Have fewer mistakes in design that have to be corrected
• Startup hours or even days faster
• Have fewer unplanned shutdowns
• Utilize the latest, most cost effective standards appropriately
• Avoid safety incidents
• Avoid environmental incidents
Who are Automation Professionals?
• Automation Professionals are:
– responsible for the direction, definition, design, development/
application, deployment, documentation, and support of systems,
software, and equipment used in control systems, manufacturing
information systems, systems integration, and operational consulting
• Work for
– End-users
– Engineering contractors
– Specialty automation and manufacturing information providers
including System Integrations and
application services divisions of supplier companies
– Hardware and Software product companies
as application engineers, sales personnel and product developers
Requirements for CAP
• Education - Experience
– Four-year technical degree (engineering, engineering technology,
computer science, math, science, etc.) + five years experience
– Two-year technical degree + eight years experience including two
years in responsible charge
– Without a degree, ten years of experience including two years in
position of responsible charge
• Exam
– Pass a comprehensive exam
• Continuing automation education
– 45 hours every three years (average of 15 hours per year)
CAP Exam
• Covers the Automation Body of Knowledge
• Difficult and comprehensive – if it wasn’t a tough exam
the certification wouldn’t mean much…
– but passable by many automation professionals,
particularly after studying less familiar topics
– Experience helps
– Pass rate is about 2/3
• Multiple choice questions
• Testing locations worldwide
• Testing available every business day and Saturdays at some
locations
Who should become CAP certified?
• People working in automation at the professional level
employed by:
– End users
– System integrators
– Engineering contractors
– Vendors
• Technical supervisors
• Technical sales personnel
• Automation educators
• ISA leaders in particular should become certified (CAP or
CCST) if their work background is appropriate -- section officers, district
officers, division officers, and society officers
What some current CAPs are saying:
• “The CAP has given me a way to prove to my employer
that I have knowledge of automation”
• “Since I don’t have a degree, becoming a CAP is the only
way I can show my next employer that I am competent in
automation”
• “I’m nearing retirement and the CAP will help me be more
attractive for part-time work”
• “In our company, people advance faster with the right
credential. CAP is that credential in the automation area”
• “My company is using CAP to demonstrate to our
customers that we have competent personnel”
Three Types of Credentials
• Certificate
– Evidence of taken course or series of courses on one subject
– Example: ISA Leadership Development Certificate Program
– Usually only requires participation
• License
– legal right to practice in broad area
– Examples: medical doctor, professional engineer
– Requires education, comprehensive exam and possibly
continuing education
• Certification
– generally narrower area than license
– Examples: Certified Opthalmologist, Project Management
Professional, Certified Automation Professional
– Requires education, experience, exam and continuing education
Hundreds of Certifications are in Use Today
• Many certifications have a legal requirement –
particularly in the health field
• Hundreds of certifications are voluntary
• Professional Engineer Registration in the U.S.
– Control System Engineering
• Certified Control System Technician
Examples of Voluntary Certifications
• Project Management Professional (PMP) – over 200,000 active,
38% outside North America
• Certified Safety Professional – 20% salary differential vs. those not
certified doing similar work - 18,000 awarded, 10% are also P.E.s
• Certified Industrial Hygienist – virtually all practitioners in this area
are certified
• Certified Manufacturing Engineer (CMfgE) – 12,000 are certified
by Society of Manufacturing Engineers
• Certified Quality Engineer (CQE)
• Certified HR Professional
Each of these certifications…
• Have been shown to increase job opportunities for those
holding the certification
• Some are essentially required to work in the respective
field in some industries or companies
• Enhances competitiveness of companies offering
services
What about the United States
Professional Engineer (P.E.) License?
• P.E. is legal license granted by states in the U.S.
• The P.E. exam can be taken in many technical areas –
so does not certify competence in any specific area
• Most states require an approved engineering degree
(generally engineering technology and computer science do not qualify)
• U. S. only
• 15% of ISA members report that they have a P.E.
• Very little automation work requires the P.E.
CSE option in the P.E. is more
specific to automation
• Control System Engineering (CSE) exam demonstrates
competence in process control --
so has similarities with certifications
BUT…
• CSE focuses only on process control area of automation
• CSE is not usually identified in the P.E. designation so is
not a good indicator of automation knowledge
• CSE will apparently never reach critical mass
– Only about 1% of automation professionals in the U.S. have passed in 14 years
– Less than 1% of ISA members report that they have passed the CSE
In automation, P.E.s and CAPs
do the same type of work, but…
• CAP demonstrates competence across the entire
automation field
• CAP includes the large number of automation
professionals with degrees in areas other than engineering
• CAP is worldwide and has worldwide credibility
• The number of CAPs will reach critical mass in a few years
CAP will be the de facto standard for demonstrating automation competence
• CAP is not a legal “license” to practice automation
Comparison to the Certified Control
System Technician®
(CCST®
)
• The job description of a CCST includes:
– Calibration
– Loop Checking
– Troubleshooting
– Start-Up
– Maintenance/Repair
– Project Organization
– Administration
• These are significantly different tasks from the project,
system design, and operation improvement tasks in the
CAP’s job description
• CCST is focused on process automation which is where
most control system technicians work

USE ONLY THE SLIDES THAT SEEM APPROPRIATE FOR YOUR AUDIENCE AND PURPOSE
Depending on the audience and purpose, you may want to have handouts of the slides you use and possibly other things from the ISA/CAP web site.
When using an abbreviated version of the slides in a presentation, you may want to eliminate or modify this slide. The note to use only the appropriate slides is to make sure that presenters look at the instructor notes. You may want to at least delete this note in the presentation version of the slides.
There are many “certificates” being given today for taking a course or a few courses. Sometimes these are called “certifications”. However, a certification recognized by certification standards groups and legally defensibly in court goes through a rigorous development process that costs hundreds of thousands of dollars. CAP is such a certification. These types of certifications become widely recognized in the field and denote broad credibility.
The Market Study referred to was run for ISA by a contractor in the summer of 2003. This study held focus group meetings and surveyed a large number of people. The results of this study were very positive and ISA used that to decide to go forward with CAP.
Again from the study in 2003.
Use this slide only for audiences that do not know ISA.
Observation of other certifications indicates that early adopters are companies and individuals who want to distinguish themselves in the market.
There are hundreds and hundreds of certifications in many other fields. Most of these have been very successful. Those that have been in existence for at some time typically now include a large percentage of the people working in that field at the highest level.
These certifications are in addition to the hundreds and hundreds of certifications that have a legal requirement. Many of the jobs in the health field have a legal requirement, for example.
Many of these certifications have done studies about the value of the certification. All those studies show significant value to the individual and in many cases to the services company that employs the person.
Many people are confused about the relationship of CAP to the P.E. The main area of confusion about the relationship of CAP to the P.E. seems to be that some think CAP is for a lesser level of work than the P.E. That is, a CAP is somewhere between a P.E. and a CCST. That is not true. Both the CAP and the P.E. are for people working at the highest level of work and the P.E. and the CAP are doing the same work.
Why have two things than: the P.E. and the CAP? The simple answer is that the P.E. does not satisfy the need for a certification with worldwide credibility that shows that the holder has broad based automation knowledge.
Some companies, particularly full-service engineering contractors, value the P.E. and automation professionals in those companies may need the P.E. to advance. Everyone who is eligible should obtain the P.E. since you never know when you may work for a company that has an internal requirement for it.
However, for essentially all automation work, there is no legal requirement that the design professional have a P.E. and the focus should be on a certification that denotes competence in automation.
The Control System Engineering exam in the Professional Engineering program is sponsored by ISA but administered by the individual states in the U.S.
Passing the CSE exam does demonstrate competence in the process control area of automation (though more people were granted CSE option in the P.E. by grandfathering that by taking the exam.)
However, having passed the CSE exam is not easily designated in the P.E. since one just says they have a P.E., not what exam they took to get it.
The CSE has been a good program for those in automation who qualify for the P.E.; particularly those whose companies want them to have the P.E. However, its growth has been so small that it will apparently never become a readily recognized credential in automation that can be used to identify those with advanced automation knowledge.
CAP demonstrates competence in automation since all CAPs take a rigorous and comprehensive exam. There is no grandfathering with CAP as there was with the CSE; that is no one gets to bypass the exam because they have been practicing a long time. The continuing education requirement in CAP also demonstrates commitment to learning new technology on an ongoing basis. (Even in those states that have a continuing education requirement for the P.E., the education does not have to be in the automation field.)
CAP covers the entire field of automation while the CSE exam in the P.E. only covers process control.
CAP does not require an approved engineering degree from a U.S. college or university. Many people working in automation at the professional level do not have an engineering degree.
Some U.S. certifications like the Project Management Professional (PMP) have had substantial growth outside the U.S. 38% of the holders of that certification are outside North America. CAP is also attracting a lot of interest outside the U.S.
As the number of CAPs increases, there will be even more focus on those with the CAP being recognized as having better capability.
A review of the job description of the CCST clearly shows that it is covering different work. Even so, a person could obtain both the CAP and the CCST.
A rough estimate is that a typical automation professional might spend 100 hours in focused study for the exam. This could include short courses, reading books, studying the CAP Learning Modules or other activities.
As a further rule-of-thumb, a short course specifically focused on CAP like the ISA three day CAP Review course would be worth double; that is the equivalent of 2 focused hours for each hour in class.
Unfocused study, like reading automation books, might be worth 0.5 X, that is it would take 2 hours of reading general automation books to be worth one focused hour.
Of course this will vary greatly depending on the experience and knowledge level of the individual. People with a lot of experience have done well on the exam with no study while others have studied a lot plus taking the three day ISA CAP Review Course.
There is no requirement that you get a certain percentage of questions right in each Category; however, the more you know about each of the Categories and Topics the better your changes. That is, if you know a lot but only about one category, you will probably not do well on the exam.
Scheduling the exam is easy on the Prometric web site. Depending on how busy your selected testing center is, you may need to schedule a few days in advance of the time you want to take the exam.
With online testing, a pass-fail result is given as soon as you complete the exam.
Work with your management to see if they can build CAP into their strategic planning for training. All it takes is for management to say that they will favor CAPs in future job promotions and salary increases. The benefit is that everyone in the group will learn new things and your customers, whether internal or external, can have greater assurance that you are a competent group.
This may be confusing so go a little slow here.
The next group of slides go through each of the seven categories listing the Topics that are in that category, and then on a subsequent slide giving a sample question that could be in that category.
The correct answer is b) gain. The gain or proportional band is the first mode that should be adjusted when tuning a three mode controller.
The correct answer is
The correct answer is b) Model Predictive Control. That control technique uses a model of the process to calculate the response the process should have to a given input, and then the value of that input is adjusted by an optimization program to give the best process response. At the next calculation time interval the entire calculation is done over so actually only the first calculated output is used.
The correct answer is b) The control recipe is unique to a batch – that is, each individual batch has a different control recipe, each of which is derived from the master recipe. The ISA 88 standard covers the batch automation area and is one of the most important standards that ISA has developed.
The correct answer is 1OO2. In this type of system, either one of two interlocks can shut down the plant. If either fails to function, then the other can do the job.
In 2OO2 or 2OO3, it is necessary for two interlocks to function to shut down the plant. That reduces the number of unnecessary shutdowns, but is less safe.
In a 1OO1 system only one interlock need function properly to shut down the plant, but there is no backup so if it fails to function, no shutdown will occur when needed.
The correct answer is b) Router. The Hub has no isolation; the Switch has no isolation and manages traffic; and the Gateway provides isolation but changes the protocol.
The correct answer is b) Profibus PA. Of course Foundation Fieldbus also will reduce wiring but that was not one of the choices. HART can reduce wiring a little because it can bring in secondary measurements from transmitters without additional wring, but the wiring is not reduced nearly as much as with a full digital fieldbus like Profibus PA.
AS-i is a discrete bus and cannot handle analog signals. 4-20 ma is all analog and has the most wiring.
The correct answer is d) Practice using the controller on a simulated system. Generally, self-study of printed material, lectures and demonstrations are not nearly as effective and retained as well as is hands-on practice.
Earned value is the estimated cost of the work completed. Generally this is the same as the percent complete times the total budget. Cost Performance Index is the earned value divided by the actual expenditure. So CPI = 40%/60% or approximately 0.67. CPI values less than 1.0 indicate that there is cost is over budget as is also obvious from fact that much more has been spend than the work done.
