ASSESSMENT: The term assessment refers to the wide variety of methods or tools that educators use to evaluate, measure, and document the academic readiness, learning progress, skill acquisition, or educational needs of students.
TYPES OF ASSESSMENT:
There are four types of assessments
1) Prognostic assessment
2) Diagnostic assessment
3) Formative assessment
4) Summative assessment

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. Interpretation of test Scores
Test Interpretation
Test Interpretation is the process of analyzing scores in a test
and translating qualitative data into quantitative and grading into
numerical. Score interpretation is same as test interpretation.
4. Scores:
“A summary of the evidence contained in an examinee's
responses to the items of a test that are related to the construct
or constructs being measured”.
Types of Scores:
Raw scores
Scales Scores
5. Raw Scores:
The number of points received on a test when the test has been
according to direction.
Example:
A Student got 10 out of a 20 scores in item quiz.
Raw scores reflect an immediate interpretation as a response to the
scores.
It does not yield a meaningful interpretation because it just raw
scores.
Thus, we have to interpret Ali’s score in a more descriptive and
meaningful way.
6. Scaled Scores:
Scaled scores are the results of transformation (usually transformed through a
consistent scale)
Examples
• A child awarded scale score of 100 is judged to have met the “National
Standard” in the area of judged by the test.
• A child awarded scale score more than 100 is judged to have exceeded
national standard and demonstrated a higher then the expected knowledge
curriculum for their age.
• A child awarded scale score less than 100 is judged to have not yet met the
“National standard” and perform below the expectation from their age.
7. Methods of Interpreting Test Scores
Referencing Framework
A referencing framework is a structure you can use to
compare student performance to something external to
the assessment itself.
Criterion Referencing Framework
Norm Referencing Framework
8. Criterion Referencing Framework
Criterion Referencing Framework permits us to describe an individual’s performance
without referring to the performance of other. Infers the kind of performance a student
can do in a domain, rather than the student’s relative standing in a norm group.
Criterion: the domain of performance to which you reference a student’s assessment
results.
Most widely used interpretation because of its ease of computation and there is a
ready transmutation table printed at the inside back cover of the teacher’s class record.
A criterion referenced interpretation of score requires a comparison of particular
student score with subjective and pre-determined performance standard (Criteria).
Criterion referenced and standard based interpretation of test result are most
meaningful when the test has been specifically designed for this purpose.
9. Criterion Referenced Interpretation
Describes student performance according to a specified domain
or clearly defined learning tasks.
Concerned with national examination and other assessment
bodies.
Used in the assessment of vocational and academic qualifications.
Results are given on a pass/fail, competent/not competent basis.
Results are conclusive and usually open to review.
10. Norm Referencing Framework
Norm referenced framework interpretation tell us how an
individual compares with other students who have taken the
same test.
How much student knows is determined by his standing or
rank within the reference group. This means that student’s
scores is not treated individually but as the part of the group
where the student belongs.
11. Norm Group
The well defined group of other students.
Basically ranking the scores of student from highest score to the
lowest one provides an immediate sample of for norm referenced
interpretation. However, barely ranking “raw scores” to interpret
student’s performance formally is not proper and valid. “The raw
scores converted to derived scores.”
Derived score
A derived score is a numerical report of test performance on a
scale that has well defined characteristics and yields normative
meanings.
12. Norm Referenced Framework
Most common types are
Grade Norms (5.5)
Percentile Norms (85% higher than)
Standard scores norms (normal curve)
Stanines (9)
13. Grade Norms:
Name of Derived Scores -----------Grade Equivalents
Grade in which student’s raw score is average.
The grade equivalent that corresponds to a particular raw
score identifies the grade level at which the typical student
obtains raw score.
Percentile Norms
Name of Derived Scores----------- Percentile Ranks
Percentile of students in the reference group who fall below
student’s raw score
14. Standard Scores Norms
Name of Derived -----------Standard Scores
Distance of student’s raw score above or below the mean of the
reference group in terms of standards units
Stanine
(Standard NINE) is a method of scaling test scores on a nine-point
standard scale with a mean of five and a standard deviation of two.
15. NORM REFERENCED
INTERPRETATION ADVANTAGES
It is very easy to use.
It is appropriate to a large group of students that is, more
than 40.
It increases the healthy competition among the students.
The teacher easily identifies learning criteria – the
percentage of students who receive highest grade or lowest
grade.
16. DISADVANTAGES
The performance of a student is not only determined by his
achievement, but also the achievement of the other students
It promotes intense competition among the students rather than
cooperation
It cannot be used when the class size is smaller than 40.
Not all the student can pass the given subject or course
17. CRITERION REFERENCED INTERPRETATION ADVANTAGES
The performance of the students will not be affected by the
of the whole class.
It promotes cooperation among the students.
All students may pass the subject or course when they meet the
set by the teacher
DISADVANTAGES
It is difficult to set a reasonable standard if it is not stated in the grading
policies of the institution
All students may not pass the subject or course when they do not meet
the standard set by the teacher or the institution.
18. Percentage
In mathematics a relationship with 100 is called percentage (denoted %). Often it is useful to
express the scores in terms of percentages for comparison.
Consider the following example:
Grade Class “A” Students % Class “B” Students %
A 10 12.50 8 40
B 25 31.25 6 30
C 30 37.50 4 20
D 15 18.75 2 10
Total 80 100 20 100
19. Standard deviation
Definition:
The standard deviation is the positive square root of the arithmetic mean
of the squares of deviations of all score from their mean.
20. Z-Score
It indicates that how many standard deviation from the mean (Plus or
minus) the student scored.
Where x is the student’s test score
µ is the mean of all test scores
σ is the standard deviation of the test scores
21. T-Score
Is the standard score with a mean equal to 50 and standard deviation is equal to 10.
Where z is an arbitrary, the given of what standard deviation does a raw score falls
the mean
Stanine Scores
The term stanine is the abbreviation of “standard nine”. It has a mean equal to 4 and
standard deviation equal to 2. A student whose raw score equals the test mean will
obtain a stanine score of 5. A score that is 3 standard deviation above the mean is
assigned a stanine of 9 not 11 because stanines are limited to a range of 1 to 9
22. Advantages of Standard Deviation
Standard scores divide differences in performance into equal intervals. For
instance, performance represented by T-Scores of 40 of 50 to 55 represent
approximately equal differences in whatever ability the test is measuring. This
attribute of equal intervals is not shared in percentile rank
Standard scores can be used to compare a student’s performance across. For
percentile rank, they should be converted to b equal-interval scale before they can
be added, subtracted, or averaged.
Standard scores can be used to compare a student’s performance across tests. For
example, if a student’s stanine scores in math and verbal skills are 4 and 2
respectively, one can conclude that the student performed better in math.
23. Limitations of Standard Deviation
Many Standard-score scales imply a degree of precision that does not exist within educational
tests. Differences of less than one-third standard deviation are usually not measurable. This
means that differences less than 3 point on the 7-score and 5 point in deviation IQ’s are not
meaningful. Both of these scales are too precise.
They represent measures of relative standing as opposed to measures of growth. A student
who progresses trough school in step with peers remains at the same number of standard
deviations form the mean. The constant standard score may suggest (incorrectly) that growth
is not occurring.
24. Ranking
The position or level something or someone has in a list that
compares their importance, quality, success.
A list that compares quality, success or importance of things or
people
A ranking is a relationship between a set of items such that, for any
two items, the first is either 'ranked higher than', 'ranked lower than'
or 'ranked equal to' the second.
25. Strategies for Assigning Ranking
Standard Competition Ranking
It is a ranking in which the mathematical values that are equal are given equal ran and the
next, lesser value is given the next highest rank.
Ordinal Ranking
It is a system of ordering where each mathematical value is given a certain position in a
sequence of numbers where no position are equal.
Fractional Ranking
It is system of ordering in which the mathematical values that are equal given the mean of
the ranking positions.
26. Frequency Distribution
In case of giving a test to the students to know about their achievements,
raw scores serve as data. It has not yet undergone any statistical
technique. To understand the data easily, we arrange it into groups or
classes. The data so arranged is called grouped data or frequency
distribution.
27. General rules for construction of
frequency distribution
The raw data is in the form of scores of fifty students:
37, 42, 44, 51, 48, 30, 47, 56, 52, 31
64, 36, 42, 54, 49, 59, 45, 32, 38, 46
53, 54, 63, 41, 49, 51, 58, 41, 48, 48
43, 37, 52, 55, 61, 43, 46, 48, 62, 35
52, 33, 46, 60, 45, 40, 47, 51, 56, 53
28. Steps:
Determine the range. Range is the difference between highest and lowest scores.
Range = 64-30 = 34
Decide the appropriate numbers of class intervals. There is no hard and fast
formula for deciding the class intervals. The number of class intervals is usually
taken between 5 and 20 depending n the length of the data. For this data the
number of class interval to be taken is 7.
Determine the approximate length of the class interval by dividing the range with
number of class intervals.
34 = 4.8 = 5
7
Determine the limits of the class intervals taking the smallest scores at the bottom
of the column to the largest scores at the top.
Determine the number of scores falling in each class interval. This is done by using
a tally or score sheet.
29. Class intervals Tallies Frequency
60-64 IIII 5
55-59 IIII I 6
50-54 IIII IIII 10
45-49 IIII IIII II 12
40-44 IIII III 8
35-39 IIII 5
30-34 IIII 4
N= 50
30. Types of Frequency
Relative Frequency Distribution
A Frequency Distribution where each of the class frequencies is
divided by the total number of observation.
Cumulative Frequency Distribution
A Frequency Distribution is the sum of class and all classes in a
frequency distribution. All that means you are adding up a value
and all of the values that comes before it.
31. Advantages And Limitations of
Frequency Distribution
Condense and summarize large amounts of data in a useful
formats
Describe all variable types
Facilitate graphic presentation of data
Begin to identify population characteristics.
Permit cautions comparison of data sets.
There are a few methods can be used in formulating class
intervals from 5-10 or over 55 & less than 30.
32. Pictoral Form
The information summarized by the frequency distribution can be
presented in graphical forms.
Both frequency polygons and histograms
are useful in describing a set of test scores
