The representativeness, recency, and size of norm samples strongly influence the accuracy of inferences drawn from their scores. Inadequate norm samples may lead to inflated or deflated scores for individuals and poorer prediction of developmental and academic outcomes. The purpose of this study was to apply Kranzler and Floyd's method for…

Assessing a high school's effectiveness is not straightforward. Comparing a school's standardized test scores to those of other schools is one approach to measuring effectiveness, but a major objection to this method is that students' test scores tend to be related to students' "socioeconomic" status--family household income, for…

A description of Developmental Coordination Disorder (DCD) is included in the "Diagnostic Manual of the American Psychiatric Association" fourth edition ("DSM-IV-TR"). The major feature of this condition is impairment in motor skill, which has a negative impact on the performance of everyday life tasks. The present review outlines major issues…

Includes two articles regarding scoring for Minnesota Multiphasic Personality Inventory scales. Comments on the advisability of utilizing normalized T scores (Hsu), and addresses these objections from a theoretical standpoint and in the context of responses from a new reference sample (Colligan, Osborne, and Offord). (LLL)

While major test publishers randomly select school districts for their national norming studies, a survey of "accepting" and "declining" districts supports the hypothesis that self-selection bias results in overrepresentation of districts which already use a specific publisher's tests or instructional materials.

Illustrates a method for generating continuously adjusted age norms using the normative data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Specific procedures for calculating age-adjusted Verbal, Performance, and Full Scale IQ scores also are demonstrated, with a worked example. Comparisons show continuous norming scores are more…

The article discusses issues relating to the international use of personality inventories, especially those in which organizations make comparisons between people from differing cultures or countries or those with different languages. The focus is on the issue of norming and the use of national versus multinational norms. It is noted that…

This research report presents new young adult norms for the Test of Adolescent/Adult Language-3 (TOAL-3) using data from the Ottawa Speech and Language Study (N=242). It is thought this population better represents the full range of young adult language abilities (because the original norms included only individuals who pursued postsecondary…

A recommendation to renorm the Bayley Scales of Infant Development is based on (1) high scores obtained on infants in rural North Carolina (N=305); (2) published means for other samples of infants born in the 1970s; (3) recent age placement revisions of items on the Gesell Developmental Examination. (Author/JW)

With psychometric tests (that is, norm-referenced tests), nearly all scores fall into one of three categories: those based on comparison with an absolute standard; those based on inter-individual comparison; or those based on intra-individual comparison. These are described and all commonly used metrics are discussed. (Author/RL)

Outlines the rationale, critical dimensions, and techniques for using peer micronorms for determining developmental delays in young children and discusses technical adequacy considerations. Case examples of the use of peer micronorms with preschool children, supplemented with hypothetical data, are used to illustrate the technique. (CR)

The feasibility of quick norms derived by the procedure described by B. D. Wright and M. H. Stone (1979) was investigated. Norming differences between traditionally calculated means and Rasch "quick" means were examined for simulated data sets of varying sample size, test length, and type of distribution. A 5 by 5 by 2 design with a…

The process of determining test norms and of using them realistically is discussed. This process involves putting meaning into a single test score by relating it to other test scores achieved by other pupils or by the same pupil at other times. The focus of attention is on the meaning of test norms; it is not on the meaning of types of test…

Addresses problems associated with Prediger's article questioning the usefulness and fairness of the unnormed Self-Directed Search (SDS) for females. Discusses issues of sex differences and same-sex test norming. (RC)

This chapter discusses units of measurement, relates types of scales and norms to the purpose for testing, looks at types of test data typically reported, identifies the primary users of test information, looks at limitations of scales and norms, and looks at the interaction between user and data.
