About this app
Ortiz Picture Vocabulary Acquisition Test™ (Ortiz PVAT™) Samuel O. Ortiz, Ph.D. The Ortiz PVAT is the first standardized, norm-referenced assessment of receptive vocabulary that can be used to fairly and accurately assess both English speakers and English learners. With unique dual norms (English Speaker norms, and English Learner norms that control for an individual’s exposure to English), the Ortiz PVAT makes it possible to evaluate an individual from any language background, or determine whether an individual’s English vocabulary performance follows expected patterns (as either a native English speaker or an English learner) or is suggestive of a language problem or disorder. Delivered in a fully digital format, the Ortiz PVAT represents a new direction in fair and standardized receptive vocabulary assessment that allows any practitioner to make valid diagnostic and intervention decisions. Key features and benefits: • Assess both English speakers and English learners (irrespective of their primary language) accurately with one, user-friendly test. • Easy English administration process that makes the Ortiz PVAT usable by any English-speaking practitioner. • English task instructions have been translated to the five most common languages spoken in the U.S. (Arabic, Chinese, Russian, Spanish, and Vietnamese) to ensure examinees with minimal exposure to English can adequately understand the task. • Exposure to English was controlled for in the creation of the English Learner norms. • Digital format (fully computerized administration and scoring). • Built-in basal (determines the appropriate starting point based on a quick screen) and ceiling (terminates the test after the examinee’s ability has been determined). • Ecologically valid visual stimuli using photographs of real objects/actions. • Pre-recorded audio with neutral pronunciation and voicing for target word presentation. • Psychometrically equivalent parallel forms (Form A and Form B) for progress monitoring.
