(DTLA-5) Detroit Tests of Learning Abilities-Fifth Edition

The Detroit Tests of Learning Abilities–Fifth Edition (DTLA-5) is the latest update to the oldest and most venerable of the tests of specific cognitive abilities. The theoretical model and constructs underlying the test were re-conceptualized based on the work of respected cognitive theorists. The DTLA-5 now includes 12 subtests: Humanities/Social Studies, Science/Mathematics, Word Opposites, Word Associations, Geometric Matrices, Geometric Sequences, Sentence Imitation, Word Span, Design Reproduction, Reversed Letters, Trail Making, and Rapid Naming. The results of the subtests can be combined to form nine composites, six representing different cognitive subdomains (Acquired Knowledge, Verbal Comprehension, Nonverbal Problem Solving, Verbal Memory, Nonverbal Memory, and Processing Speed); two representing larger cognitive domains (Reasoning Ability and Processing Ability); and a global composite, representing general cognitive ability, which is formed by combining the results of all 12 of the DTLA-5 subtests. Examiners can administer the subtests from one or both of the DTLA-5 domains, depending on the purpose of the evaluation.

Features of the DTLA-5 include:

• The Story Sequences, Story Construction, and Design Sequences subtests were eliminated and 7 new subtests were added: Humanities/Social Studies, Science/Mathematics, Word Associations, Geometric Matrices, Geometric Sequences, Trail Making, and Rapid Naming.
• The DTLA-5 norms are based on an unweighted sample of 1,383 students between 6 years and 17 years, 11 months who were tested from 2013 to 2015.
• New and extensive studies of the floors, ceilings, and item gradients for the DTLA-5’s subtests and composites were conducted.
• Access to the all-new DTLA-5 Online Scoring and Report System is now included with each purchase of the DTLA-5 Complete Kit and with the purchase of every replacement pack of Examiner Record Booklets.
