Commercially available tests published in English or Spanish that are submitted to us are described in Tests in Print and Pruebas Publicadas en Español, respectively. Tests in English that provide at least minimal psychometric documentation (e.g., development history, reliability estimates, evidence of test score validity) are eligible for review in the Mental Measurements Yearbook series. Descriptive listings and reviews of tests in English that meet our review criteria are included on our Test Reviews Online search engine. In addition, our databases are offered in several formats via electronic subscription services (see our Test Reviews & Information page for details).
