Content validity refers to how well a test measures the specific skills or knowledge it is intended to assess, such as the content of a particular course. Construct validity is the degree to which a test measures the underlying attribute it claims to measure. Predictive validity is the ability of a test to forecast future performance or behavior, while concurrent validity examines the correlation between a test's results and those of another valid test given at a similar time.

Properties of-assessment-methods
This document discusses key properties of assessment methods: validity, reliability, fairness, practicality and efficiency, and ethics. It defines validity as the degree to which a test measures what it is intended to measure. There are several types of validity including content, predictive, criterion, and construct validity. Reliability refers to an assessment producing stable and consistent results over time. Fairness means students understand what is being assessed and the method, and that assessment is used for learning not weeding out students. Practicality considers if teachers understand the assessment, it is not too complex, and can be implemented. Ethics refers to conducting assessments in a manner that conforms to professional standards of right and wrong.
Properties of Assessment Method
This document discusses key properties that make assessments valid, reliable, fair, practical and ethical. It defines validity as the degree to which a test measures what it is intended to measure. There are several types of validity including content, criterion, predictive and construct validity. Reliability refers to an assessment producing stable and consistent results over time and is measured through inter-rater reliability, test-retest reliability and internal consistency. Fairness means students understand learning targets and the assessment method. Practicality means teachers are familiar with assessments and they are not overly complicated to implement. Ethics in assessment refers to ensuring tests are fair and conform to professional standards of conduct.
Assessment of Learning
This document discusses assessment validity and reliability in technical and vocational education. It defines validity as whether a test measures what it is intended to measure and reliability as whether a test yields consistent results. There are three types of validity evidence: content, criterion, and construct validity. Content validity ensures test items adequately cover the domain. Criterion validity shows a test can predict future performance. Construct validity demonstrates a test captures the intended concept by correlating with similar tests and not correlating with dissimilar tests. The document also discusses standardized vs teacher-made tests and different forms of validity evidence like predictive, concurrent, convergent, and divergent validity.
Validity, Reliability and Feasibility
This document discusses validity, reliability, and feasibility in data collection. Validity refers to how well a test measures what it intends to measure and includes content, construct, and criterion-related validity. Reliability is the consistency of results and includes test-retest, parallel forms, and split-half reliability. Factors like time interval, test conditions, length, and difficulty influence reliability. A test must be both valid and reliable. Feasibility refers to practical aspects like how easy a test is to design, administer, score, and interpret results.
Rubrics
Rubrics are tools that define the criteria and grading standards for assessments and assignments. They communicate expectations and allow for objective evaluation. There are two main types: holistic rubrics provide a single overall score based on impression, while analytic rubrics break assignments into components and score each separately, providing more detailed feedback. Both help instructors grade consistently and clarify expectations for students.
Criteria to Consider when Constructing Good tests
The document discusses criteria for constructing valid and reliable tests. It defines validity as the degree to which a test measures what it intends to measure. Important factors in validity include appropriateness, difficulty level, and construction of test items. Reliability refers to consistency of scores when retaking the same test. Factors like length, difficulty, and objectivity affect reliability. Various methods are provided for establishing validity and reliability statistically, including calculating correlations between tests. Formulas are also presented for computing measures of central tendency, variability, and determining the shape of frequency distributions.
Characteristics of a good measuring tool
The document outlines the key characteristics of a good measuring tool, including validity, reliability, practicability, measurability, and objectivity. Validity refers to a test measuring what it claims to measure. Reliability is the consistency of a measurement under the same conditions. Practicability considers ease of use, administration, and cost. Measurability is measuring intended objectives. Objectivity means results are obtained the same by different scorers.
Rubric Development
A rubric is a systematic method for providing feedback and evaluation of student work. It establishes clear expectations and criteria for assessing student performance. There are typically three parts to a rubric: the performance criteria, the levels of achievement, and a scoring guide. When designing a rubric, the key criteria for the assignment should be determined based on aspects like the communicator, audience, purpose, and context. Rubrics can be analytic, evaluating different components separately, or holistic, providing an overall score. Rubrics should be shared with students upfront and used to guide assessment and feedback.

Criteria for Good Assessment - John Norcini, Ph.D.
Good assessments should demonstrate validity, reliability, and equivalence. The appropriate characteristics depend on the assessment's purpose (formative or summative) and stakeholders (learners, teachers, patients, regulators). Formative assessments aim to enhance learning and should strongly exhibit catalytic and educational effects, while summative assessments evaluate learning and require high validity, reliability, and equivalence. Stakeholder priorities also vary, such as learners prioritizing educational effect and regulators prioritizing validity.
Brm Measurement
Reliability refers to the consistency and reproducibility of measurement results. There are two main ways to evaluate reliability: test-retest reliability, which measures consistency over time using the same respondents, and equivalent form reliability, which uses two similar questionnaires to measure internal consistency. Validity refers to how well a measurement scale measures what it intends to measure. It can be evaluated through face validity, which assesses expert agreement, and content validity, which evaluates whether the scale covers all aspects of the concept being measured.

Validity and objectivity of tests
Validity refers to whether a test measures what it intends to measure. There are several types of validity including content, construct, criterion-related (concurrent and predictive), and face validity. Objectivity means the degree to which different scorers arrive at the same score and is important for validity and reliability. Ensuring objectivity in test construction and scoring can help reduce bias.
Standardized and non standardized tests
Standardized and non-standardized tests are used to assess students. [1] Standardized tests are administered uniformly with set procedures for scoring and interpretation, while non-standardized tests do not have uniform procedures. [2] For accurate measurement, tests must be valid, reliable, and usable to provide dependable results. [3] Different types of tests include essay tests which allow freedom of response and evaluate complex learning outcomes.
Standardized and non standardized tests
Here are three examples of standardized tests:
1. SAT (Scholastic Assessment Test) - A standardized test widely used for college admissions in the United States. It is administered by the College Board and measures skills in math, reading, and writing.
2. ACT (American College Testing) - Another standardized test used for college admissions in the US. It measures skills in English, math, reading, and science.
3. TOEFL (Test of English as a Foreign Language) - A standardized test to measure the English language ability of non-native speakers wishing to enroll in English-language institutions. It measures reading, listening, speaking, and writing skills.
Validity
This document discusses different types of validity in testing:
1. Content validity refers to how well a test measures the specific construct it aims to assess. A test needs to be related to the relevant class content.
2. Criterion-related validity is the degree of agreement between a test and an independent, reliable standard. There are two types: concurrent and predictive validity.
3. Construct validity provides evidence that test items measure the intended underlying abilities. Think-aloud and retrospection methods can provide evidence of construct validity.
Validity in scoring and face validity are also discussed. To improve validity, test specifications and a representative sample of content should be used, and scoring should directly relate to what

Test evaluation
This document discusses different types of testing validity and reliability. It defines reliability as the consistency of test measures over time and contexts. It then defines validity as how well a test measures what it intends to, and describes various types of validity including face validity, content validity, construct validity, criterion validity, concurrent validity, predictive validity, and practicality validity.
Validity and Reliability of a Test
Validation and reliability are important concepts for determining the quality of a test. There are three main types of validation evidence: content-related, criterion-related, and construct-related evidence. Content-related evidence examines how well the test covers the intended content area. Criterion-related evidence looks at how scores on the test correlate with other measures. Construct-related evidence determines how well the test measures the intended psychological construct. Reliability refers to the consistency of scores and is measured using reliability coefficients, with coefficients above 0.8 indicating good reliability for classroom tests.
VALIDITY
The document discusses various types of validity in psychometrics and research. It defines validity as the degree to which a test measures what it claims to measure. The main types of validity discussed are content validity, criterion-related validity (including concurrent and predictive validity), construct validity, and face validity. Content validity refers to how well a test represents the domain it is intended to measure. Criterion-related validity compares test scores to external outcomes. Construct validity examines if a test aligns with theoretical constructs. Face validity is simply whether a test appears valid at face value.
Characteristics of Good Evaluation Instrument
1. Validity, reliability, objectivity, adequacy, discrimination power, practicability, comparability, utility, and comprehensiveness are key characteristics of a good evaluation instrument.
2. Validity refers to a test accurately measuring what it is intended to measure. Reliability is consistency in a test's measurements. Objectivity means a test's scores are not affected by scorers' biases.
3. Other important characteristics include a test being adequate to measure objectives, able to discriminate levels of performance, practical to administer, allowing comparability of scores, useful for its intended purpose, and comprehensive in assessing objectives.
Standardized and non standardized tests (1)
This document discusses standardized and non-standardized tests. Standardized tests are administered and scored in a consistent manner to all test takers. They are developed by test specialists and allow for comparison of performance between individuals. Non-standardized tests focus on a student's attainment at a point in time and are often teacher-made. The document outlines key characteristics of good tests such as reliability, validity, cost, time, acceptability, objectivity, and usability. It also discusses norms, which provide a standard of comparison for test results.
Measurement & Evaluation pptx
- Standardized tests are formal assessments administered under standardized conditions to large groups of students. They provide norm-referenced scores allowing comparison between students. Teacher-made tests are informal classroom assessments created by teachers.
- Standardized tests have established reliability and validity ensured through rigorous test construction procedures. Teacher tests may vary in reliability and validity.
- Standardized test results provide information on student achievement compared to peers. Teacher tests provide information on mastery of specific classroom content.
Validity of test
This document discusses different types of validity including content validity, criterion validity, and construct validity. It provides definitions and steps for establishing each type of validity. Specifically, it explains that content validity determines if a test adequately measures the intended content area. Criterion validity compares test scores to an external outcome measure concurrently or predictively. Construct validity establishes if a test measures a theoretical construct through examining correlations between various measures of that construct. The document also notes factors that can impact a test's validity such as length, ability range, and ambiguous directions. Overall, the document provides an overview of establishing and interpreting different aspects of test validity.

Validity
- 2. The single most important characteristic of a test. The degree to which a test measures what it is supposed to measure.
- 4. Content Validity The degree to which test items match some objective criterion, such as content of a course or textbook, the skills to do a certain job, or knowledge deemed essential for some purpose. Usually established by comparing the knowledge, skills, and values tested by the test items and those covered in the syllabus/ course of study or textbook.
- 5. Construct Validity The degree to which a test measures an attribute or quality it is supposed to measure High when a test not only correlates with other measures with which it is supposed to correlate, but also fails to correlate with measures of the concepts, from which it is supposed to be different.
- 6. Predictive Validity The degree or extent to which scores on a test can predict later behavior or test scores.
- 7. Concurrent Validity The degree of relationship between scores on a test or scale and scores on another measure of established validity given at about the same time.
