Obtain a quick assessment of adults' nonverbal intellectual abilities to minimise need for long range skill to assess intelligence. Beta-4 is easy to administer and score and is useful for screening large numbers of people for whom administering comprehensive test batteries would be time-consuming and costly. It is especially useful when assessing low-functioning or low-skilled individuals. Beta-4 can be administered by group or individually.
Beta-4 is the latest revision of an instrument with a long and distinguished history. The original version was developed by the U.S. Army during World War I to assess the intellectual ability of illiterate recruits. In 1934, Kellogg and Morton revised it to make it suitable for civilian use. Beta-4 is an updated version of the Beta-III Examination, Third Edition, published in 1999.
The test has a variety of occupational and educational applications and is great for use with diverse adult populations within a wide range of language skills and intelligence levels. Appropriate uses include prison systems assessing the intellectual ability of inmates, companies evaluating the employment readiness of potential new hires, and vocational schools determining placement of students. Beta-4 is also appropriate for use with ESL individuals, as no reading is required.
Now Even Easier to Use
This leading adult nonverbal assessment is even better. Professionals familiar with Beta III can administer Beta-4 with ease. Technicians, paraprofessionals, and others in the fields of psychology and education can also administer Beta-4 with training and supervision. It is easily hand-scored with a key.
Reliable and Valid
Extensive reliability and validity studies were conducted with Beta-4. The norm sample includes approximately 1,095 adults. Validation data were collected using individuals with specific group samples, including mild/moderate intellectual disability, gifted and talented, corrections, substance abuse, TBI and ADHD. The standardisation sample was stratified by age, gender, race/ethnicity, educational level, and geographic region according to 2010 census data.
Beta-4 was validated using other well-known tests, including the Beta III, WAIS®-IV, Wechsler Fundamentals Academic Skills.
Includes clinical studies for:
- Mild/moderate intellectual disability
- Gifted and talented
- Substance abuse
