Strengths
• Efficient• Flexible Administration Format
• Group• Individual
• Multiple Tests• Nonverbal• Easy to Use• Low Floor
Applications
• Assess nonverbal intellectual ability of adolescents and adults.• Quick estimate of general intellectual ability• Industrial organizations hiring large numbers of unskilled workers• Occupational rehabilitation & Job Training Programs• Identify academic problems in individuals with low nonverbal ability• Evaluate specific cognitive deficits that may contribute to low academic
achievement• Predict future academic achievement• Correctional Settings

Applications: Correctional Settings• Required mental health screening often includes intelligence
assessment.• Assess intelligence in order to maximize use of additional program
resources. • NCCHC standards state that post-admission mental health
assessment should include intelligence tests to screen for intellectual disability among inmates.
• ABA recommends initial screening to identify potential security risks including vulnerability to abuse.
• ABA also recommends screening upon admission to identify issues requiring immediate assessment or attention…[to include] special education eligibility.

Administration
• Approximately 25-30 minutes• One proctor for every 15 examinees• Adequate space for group administration• Establish rapport prior to testing• Reschedule late arrivals or those who have extreme difficulty
understanding the directions or practice problems.• Test in only one language in a single group session.
Administration guidelines continued
Time limits• Use timing device and strictly adhere to time limits.
Coaching• Coaching invalidates results; be careful not to hint at responses.
Guessing• Encourage examinee to take best guess if necessary.
Erasing• Permitted, but may need to remind that some difficulty is normal.
Skipping• Encourage examinee to take their best guess rather than skipping.

5 Tests
Test Abbreviation Time Limit Description
Coding CD 2 minutes Using a key, the examinee writes the numbers that correspond to geometric-like symbols.
Picture Absurdities
PA 3 minutes The examinee draws a mark (/) through the one picture out of four that shows something that is illogical or foolish.
Clerical Checking
CC 2 minutes The examinee circles the equal (=) or not equal (≠) sign to indicate if pairs of pictures, symbols, or numbers are the same or different.
Picture Completion
PC 2 minutes 30 seconds
The examinee draws what is missing to complete a picture.
Matrix Reasoning
MR 5 minutes The examinee chooses the missing symbol or picture that best completes a set of four symbols or pictures.
Scoring
1. Calculate Test Total Raw Scores
2. Convert Total Raw Scores to Scaled Scores
3. Derive the Beta-4 IQ Score

Ability-Achievement Analysis for the Identification of a Specific Learning DisabilitySimple-Difference method:• Subtract Wechsler Fundamental: Academic Skills standard score from
the Beta-4 IQ score. • Consider statistical significance of the difference and the frequency
(base rate).
Predicted-difference method:• Uses the ability score in a regression equation to predict the expected
achievement score.
