Administration and Scoring
The SIT-4 is verbally administered so it does not penalize individuals who are methodical, fearful, or have reading disabilities. Crystallized verbal intelligence has the highest overall correlation to mental ability, and is widely used to assess gifted and talented, as well as abilities of the intellectually disabled. Since items are administered and scored simultaneously, the test can be given in a brief period of time. The SIT-4 yields a Total Standard Score, charts category standard scores, and compares ability to achievement.
The RIST-2 quickly and reliably identifies individuals who may need a more comprehensive intelligence assessment.
The RIPA-Geriatric: 2nd edition is a comprehensive assessment battery designed to identify, describe, and quantify cognitive-linguistic deficits in the geriatric population.
The Executive Functions Test-Elementary: Normative Update assesses how students use language in various executive functions, such as working memory, problem solving, inferring, predicting outcomes, and shifting tasks.
The CTONI-2 (2009 revision) is a popular norm-referenced test that uses nonverbal formats to measure general intelligence of children and adults whose performance on traditional tests might be adversely affected by subtle or overt impairments involving language or motor abilities.
TIPS assesses how information (either visual or auditory) is processed and retained (in sequence or not) in persons 5 - 90+ years. Delayed recall, semantic fluency, and the effects of interference on recall and learning are also quantified.
The BRIEF-2 is a set of questionnaires for parents, teachers, and now older students (ages 11-18), designed to evaluate executive function from multiple perspectives.
