Glossary


ABAP  (American Board of Assessment Psychology), 28, 64
ABPP  (American Board of Professional Psychology), 28
Alternate assessment  An evaluative or diagnostic procedure or process that varies from the usual, customary, or standardized way a measurement is derived, either by some special accommodation made to the assessee or by alternative methods designed to measure the same variable(s), 4-6, 484-485
Behavioral observation  Monitoring the actions of others or oneself by visual or electronic means while recording quantitative and/or qualitative information regarding the actions, typically for diagnostic or related purposes and either to design intervention or to measure the outcome of an intervention, 10, 393, 542
Case history data  Records, transcripts, and other accounts in written, pictorial, or other form, in any media, that preserve archival information, official and informal accounts, and other data and items relevant to an assessee, 9-10, 417, 455
Construct  An informed, scientific idea developed or generated to describe or explain behavior; some examples of constructs include "intelligence," "personality," "anxiety," and "job satisfaction," 14, 173
Diagnosis  A description or conclusion reached on the basis of evidence and opinion through a process of distinguishing the nature of something and ruling out alternative conclusions, 17-18, 409-410
Diagnostic test  A tool used to make a diagnosis, usually to identify areas of deficit to be targeted for intervention, 17-18, 306-308
Erg  A unit of work, 27n
Ergonomics  The study of work, 27n
Error  Collectively, all of the factors other than what a test purports to measure that contribute to scores on the test; error is a variable in all testing and assessment, 18
Error variance  In the true score model, the component of variance attributable to random sources irrelevant to the trait or ability the test purports to measure in an observed score or distribution of scores. Common sources of error variance include those related to test construction (including item or content sampling), test administration, and test scoring and interpretation, 18, 129
Format  A general reference to the form, plan, structure, arrangement, or layout of test items as well as to related considerations such as time limits for test administration, 6.
Interview  A tool of assessment in which information is gathered through direct, reciprocal communication, 8-9, 410-417
Measurement  Assigning numbers or symbols to characteristics of people or objects according to rules, 15-16, 73
Norms  The plural of norm, also referred to as normative data; the test performance data of a group of testtakers, designed as a reference for evaluating, interpreting, or otherwise placing in context individual test scores, 30, 100-112
Portfolio  A work sample; referred to as portfolio assessment when used as a tool in an evaluative or diagnostic process, 9, 318
Protocol  (1) The form or sheet on which test taker's responses are entered; (2) a method or procedure for evaluation or scoring, 22n
Psychological assessment  The gathering and integrating of psychological data for psychological evaluation, through the use of tests, interviews, case studies, behavioral observation, and specially designed apparatuses and measurement procedures; contrast with psychological testing, 4
Psychological test  A measuring device or procedure designed to measure psychology-related variables, 6
Psychological testing  The measuring of psychology-related variables by means of devices or procedures designed to obtain samples of behavior, 4
Psychometrics  The science of psychological measurement (synonymous with the antiquated term psychometry), 29
PsycINFO  An online electronic database maintained by the American Psychological Association and leased to institutional users, designed to help individuals locate relevant documents from psychology, education, nursing, social work, law, medicine, and other disciplines, 35
Rapport  A working relationship between examiner and examinee in testing or assessment, 22-23
Reliability  The extent to which measurements are consistent or repeatable; also, the extent to which measurements differ from occasion to occasion as a function of measurement error, 29, 32, 128-153
Role play test  An assessment tool wherein assessees are instructed to act as if they were placed in a particular situation, 10-11 Rorschach inkblot test, 43, 368-372
Scale  (1) A system of ordered numerical or verbal descriptors, usually occurring at fixed intervals, used as a reference standard in measurement; (2) a set of numbers or other symbols whose properties model empirical properties of the objects or traits to which numbers or other symbols are assigned, 16, 73-76, 194
Scaling  (1) In test construction, the process of setting rules for assigning numbers in measurement; (2) the process by which a measuring device is designed and calibrated and the way numbers (or other indices that are scale values) are assigned to different amounts of the trait, attribute, or characteristic measured; (3) assigning numbers in accordance with empirical properties of objects or traits, 16, 193-198
Score(s)  A code or summary statement, usually but not necessarily numerical, that reflects an evaluation of the performance on a test, task, interview, or other sample of behavior, 6
Scoring  The process of assigning evaluative codes or statements to performance on tests, tasks, interviews, or other behavior samples, 6-7
Standard error of measurement  In true score theory, a statistic designed to estimate the extent to which an observed score deviates from a true score; also called the standard error of a score, 19, 148
State  As in personality state, (1) the transitory exhibition of a trait, indicative of a relatively temporary predisposition to behave in a particular way; (2) in psychoanalytic theory, an inferred psychodynamic disposition designed to convey the dynamic quality of id, ego, and superego in perpetual conflict, 13, 14-16, 328
Test  A measuring device or procedure, 6-8
Trait  Any distinguishable, relatively enduring way in which one individual varies from another; contrast with state, 13-14
Validity  A general term referring to a judgment regarding how well a test or other measurement tool measures what it purports to measure; this judgment has important implications regarding the appropriateness of inferences made and actions taken on the basis of measurements, 29-30, 32-33, 154-186
