This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

Oral language skills are important to consider in school psychology practice, as they are directly tied to many areas of academic functioning. For example, research has demonstrated that oral language skills in early elementary school predict reading comprehension in later grades (Kendeou, van den Broek, White, & Lynch, 2009). With a…

Reviews 12 studies to determine whether coaching improves student performance on the Scholastic Aptitude Test (SAT). While results are mixed, evidence suggests that coaching does not appreciably improve students' verbal or math scores. Factors such as test reliability and weighting SAT scores with high school records should be considered. Includes…

Investigation of the stability of Wechsler Adult Intelligence Scale Revised scores of 25 college students over a 4-year period found that global and subtest scores were highly stable. Subtest scores tended to be higher on the retest, but global scores were not despite four years of educational experiences between test administrations. (Author/DB)

This research brief summarizes the available reliability and validity data available in, but spread throughout, a number of General Educational Development (GED) Testing Service publications. A section on reliability discusses how to determine reliability of a test's scores and two ways of assessing the reliability of a test--internal consistency…

Higher elementary student scores on standardized tests do not mean educational improvement. Scores can be affected by teaching "to" the test, coaching on test taking, and skewed norms. Test scores have been declining at the secondary level. Included is a discussion of secondary tests. (MD)

This study explored whether standard administration and scoring of conventional articulation tests accurately identified 20 children (ages 5-9) as phonologically disordered and whether test data established severity levels and programing needs. Tests correctly identified the phonological disorders but failed to reliably differentiate severity…

This manual summarizes technical information regarding the 1982 Stanford Achievement Test, Seventh Edition when administered to hearing-impaired students. In Section 1, the procedures used to select the norming sample (7,557 hearing-impaired students) are described, and the demographic characteristics of the resulting sample are compared to those…

Interest in and use of the System of Multicultural Pluralistic Assessment's (SOMPA's) Health History Inventories (HHI) has been intensive despite the unavailability of psychometric data estimating its stability. This paper reports the results of a longitudinal study designed to provide data on the stability of the HHI over a four year period. The…

The New Jersey College Basic Skills Placement Test (NJCBSPT) is designed to measure certain basic language and mathematics skills of students entering New Jersey colleges. The primary purpose of the two mathematics sections is to determine whether students are prepared to begin certain college-level work without a handicap in computation or…

This bulletin describes the technical adequacy of the Florida Teacher Certification Examination and includes discussions on establishing test reliability, test validity, passing scores, and protecting the test from cultural or ethnic bias. Chapter I describes the development of the examination: (1) development, identification, and validation of…

The first edition of this book was written to give information about testing to people whose work gave them access to test results, but whose training included little or nothing about the use and interpretation of tests. Later editions have been intended for a broader audience as the need for understanding what test scores really mean has…

This report describes two studies, one comparing Florida students' performance to national norms on the General Educational Development (GED) tests, the other comparing performance on the GED tests and the Florida State Student Assessment Test, Part II (SSAT-II). In the first study, a representative sample of 1,200 high school seniors completed…

This guide--written for school administrators, teachers, counselors, parents, and the community--describes educational tests and measurements and test-related statistics. While specifically intended to help readers interpret the tests administered in the Los Angeles (California) Unified School District, this information may also be used to…
