A PARAMETER  look up translate image
In item response theory (IRT), the a parameter is a number that indicates the discrimination of a test item a" how sharply the item differentiates between generally strong and generally weak test takers. If the a parameter for an item is large, the probability that the test taker will answer the item correctly increases sharply within a fairly narrow range of ability. If the a parameter is small, the probability of a correct answer increases gradually over a wide range of ability.
ABILITY  look up translate image
The knowledge, skills or other characteristics of a test taker measured by the test.
ABILITY / TRAIL PARAMETER  look up translate image
In item response theory (IRT), a theoretical value indicating the level of a participant on the ability or trait measured by the test; analogous to the concept of true score in classical test theory.
ABILITY TESTING  look up translate image
The use of standardized tests to evaluate the current performance of a person in some defined domain of cognitive, psychomotor, or physical functioning.

ACHIEVEMENT LEVELS / PROFICIENCY LEVELS  look up translate image
Descriptions of student or adult competency in a particular subject area, usually defined as ordered categories on a continuum, often labeled from "basic" to "advanced," that constitute broad ranges for classifying performance.
ADAPTIVE TESTING  look up translate image
A sequential form of individual testing in which successive items in the test are chosen based primarily on the psychometric properties and content of the items and the participant's response to previous items.
ADJUSTED VALIDITY / RELIABILITY COEFFICIENT  look up translate image
A validity or reliability coefficient -- most often, a product-moment correlation -- that has been adjusted to offset the effects of differences in score variability resulting from different populations. See restriction of range or variability.
ADL  look up translate image
In 1997, the US DoD and the White House Science and Technology Bureau launched the Advanced Distributed Learning initiative. ADL was targeted from the very beginning to Web-based education. Its work is coordinated with other organizations like IEEE, IMS and AICC. As a result of this joint work, it was produced the Sharable Courseware Object Reference Model (SCORM). This proposal includes a reference model for educational sharable software objects, a runtime environment and a content aggregation model.
ADMINISTRATIVE INDEPENDENCE  look up translate image

AGE EQUIVALENT  look up translate image
The chronological age population for which a given score is the average score. Thus, if children ten years and six months of age have a median score of 17 on a test, the score 17 is said to have an age equivalent of 10-6.
AICC  look up translate image
The Aviation Industry CBT Committee is the natural response to the educational standardization challenge from one of the largest users of educational software. The activities of the AICC are targeted, among others, to the definition of software and hardware requirements for student computers, needed peripherals, multimedia formats for course contents, and user interface properties.

Advanced Learning Infrastructure Consortium (ALIC) is a collaborative effort of the Japanese government and the industry and academic professionals working on e-learning field.
ALPHA COEFFICIENT  look up translate image
A statistic that is used to estimate the reliability of scores on a test. What alpha actually measures is internal consistency a" the extent to which the test takers performed similarly on all the items. Under some assumptions that are usually reasonable, alpha also indicates the extent to which those test takers would perform similarly on two different forms of the same test. The alpha coefficient is commonly used to indicate the reliability of scores on tests in which the questions all measure...(more)
ALTERNATE FORMS  look up translate image
Two or more versions of a test that are considered interchangeable, in that they measure the same constructs, are intended for the same purposes, and are administered using the same directions. Alternate forms is a generic term used to refer to any of three categories. Parallel forms have equal raw score means, equal standard deviations, and equal correlations with other measures for any given population. Equivalent forms do not have the statistical similarity of parallel forms, but the dissimilarities...(more)
ANALYTIC SCORING  look up translate image
A procedure for scoring responses on a constructed-response test, in which the scorer awards points separately for specific features of the response. (Compare with holistic scoring.)
ANALYTIC SCORING PROCEDURE  look up translate image
A procedure in which the judgment of each critical dimension of performance is undertaken separately and the resultant values re combined for an overall score. In some instances, scores on the separate dimensions may also be used in interpreting performance.
ANCHOR TEST  look up translate image
A common set of items administered with each of two or more different forms of a test for the purpose of equating the scores of these forms.
ANSWER KEY  look up translate image
The key that describes the scoring scenario for a question or test.
APPEAL  look up translate image
Request by applicant, candidate or certified person for reconsideration of any adverse decision made by the certification body related to her/his desired certification status.
APPLICANT  look up translate image
An individual who declares interest in earning a credential offered by a certification program, usually through a request for information and the submission of materials. See Candidate.
ARIADNE  look up translate image
The Alliance of Remote Instructional Authoring and Distribution Networks for Europe was part of the European Commission's fourth framework program.

The methods for determining if candidates possess the necessary knowledge and/or skills related to the purpose of the certification.
ASSESSMENT, TEST, EXAMINATION  look up translate image
These terms all refer to devices or procedures for getting information about the knowledge, skills or other characteristics of the people being assessed, tested or examined. The three terms are often used interchangeably, but there are some differences between them. "Assessment" is the broadest of the three terms; "examination" is the narrowest.
ATTENTION ASSESSMENT  look up translate image
The process of collecting data and making an appraisal of a person's ability to focus on the relevant stimuli in a situation. The assessment may be directed at mechanisms involved in arousal, sustained attention, selective attention and vigilance, or limitation in the capacity to attend to incoming information.
AUTHORING SYSTEM  look up translate image
A generic name for one or more computer programs that allow a user to author, and edit items (i.e. questions, choices, correct answer, scoring scenarios and outcomes) and maintain test definitions (i.e. how items are delivered with a test).
AUTOMATED NARRATIVE REPORT  look up translate image

AUTONOMY  look up translate image
Control over all essential certification and re-certification decisions without being subject to approval by or undue influence from any other body. See Administrative Independence.
B PARAMETER  look up translate image
In item response theory (IRT), the b parameter is a number that indicates the difficulty of a test question. In general, a higher b parameter indicates a more difficult test question.
BATTERY  look up translate image
A set of tests standardized on the same population, so that norm-referenced scores on the several tests can be compared or used in combination for decision making.
BIAS  look up translate image
In a statistical bias context, a systematic error in a test score. In a fairness bias context, bias may refer to the inappropriateness of content in the assessment instrument, either in terms of its irrelevance, overemphasis, exclusion, under representation, irrelevant components in the construct of test scores. Fairness Bias usually favors one group of participant over another. In a eligibility bias context, bias refers to the inappropriateness or irrelevance of requirements for certification...(more)
BILINGUAL  look up translate image
The characteristic of being relatively proficient in two languages.
BISERIAL CORRELATION  look up translate image
A statistic used at ETS to describe the relationship between performance on a single test item and on the full test. It is an estimate of the correlation between the test score and an unobservable variable assumed to determine performance on the item and assumed to have a normal distribution (the familiar "bell curve"). Compare to correlation, point biserial correlation.
