Chapter Highlights What makes a good test? Test reliability Interpretation of reliability information from test manuals and reviews Types of reliability estimates Standard error of measurement Test validity Methods for conducting validation studies Using validity evidence from outside studies How to interpret validity information from test manuals and independent reviews. Principles of Assessment Discussed Use only reliable assessment instruments and procedures. Use only assessment procedures and instruments that have been demonstrated to be valid for the specific purpose for which they are being used. Use assessment tools that are appropriate for the target population.
A basic knowledge of test score reliability and validity is important for making instructional and evaluation decisions about students. Since instructors assign grades based on assessment information gathered about their students, the information must have a high degree of validity in order to be of value. Assessment data collected will be influenced by the type and number of students being tested. This variance in student groups from semester to semester will affect how difficult or easy test items and tests will appear to be. This variance in scores from group to group makes reliability and validity an important consideration when developing and administering assessments and evaluating student learning.

The major conclusion drawn was the need for teacher training in the use and interpretation of assessment data. Published on July 3, by Fiona Middleton. The paper has been written for the novice researcher in the social sciences. Consider how to update or improve the ways in which they currently collect validity and reliability evidence. The aim of the study was to examine the importance of reliability and validity as necessary foundation for fair assessment. This study shows that Johor VC students are highly potential in co-curricular. Reliability is a very important piece of validity evidence.
The reliability of an assessment tool is the extent to which it measures learning consistently. The validity of an assessment tool is the extent by which it measures what it was designed to measure. The reliability of an assessment tool is the extent to which it consistently and accurately measures learning. No results, however, can be completely reliable. There is always some random variation that may affect the assessment, so educators should always be prepared to question results.
PDF | Assessment for learning is a new perspective on the assessment system in education. The traditional practice is for evaluating outcomes.
An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data. Dr Hans Wagemaker was the executive director of the International Association for the Evaluation of Educational Achievement for 17 years, responsible for the management of all IEA international research and assessment projects and activities.
