The author provides a checklist for educators who are selecting technically adequate tests for identifying and referring students for gifted education services and programs. The checklist includes questions related to how the test was normed, reliability and validity studies as well as questions related to types of scores, administration, and…

Purpose: The Vocal Tract Discomfort Scale (VTD Scale) is a self-rating questionnaire investigating physical symptoms in the larynx associated with vocal pathology. The aim of this work was to investigate the reliability, validity, sensitivity, and specificity of the first German version and to provide normative data with thresholds for pathology…

The Cambridge Face Memory Test Long (CFMT+) is used to investigate extraordinary face recognition abilities (super-recognizers [SR]). Whether lab and online presentation of the CFMT+ lead to different test performance has not yet been investigated. Furthermore, we wanted to investigate psychometric properties of the CFMT+ and the Glasgow face…

This study is a systematic review designed to identify the instruments most frequently used to evaluate children's development, describe their operational and psychometric characteristics and determine which are the most accurate. We carried out a systematic search of the online databases PsycINFO and PubMed Central using the descriptors…

Recently, Nissen et al. argued in this journal for the use of Cohen's d, in place of the more commonly used normalized gain, in the analysis of preinstruction and postinstruction scores on concept inventories used to measure the effectiveness of instruction. Their reason for advocating such a change is that they say normalized gains are…

The interpretation of psychometric test results is usually based on norm scores. We compared semiparametric continuous norming (SPCN) with conventional norming methods by simulating results for test scales with different item numbers and difficulties via an item response theory approach. Subsequently, we modeled the norm scores based on random…

The aim of the present study is to develop a national non-verbal cognitive ability test in Turkey. Test items were developed during the first stage and applied as a pilot study on 3,073 children in the age interval of 4 to 13. The test was given its final form based on the values of item difficulty, item distinctiveness, item total score…
