Wrap-up

About I/O Solutions

National public safety test publisher and consulting firm based in Chicago

Staff of ten consultants trained in Industrial/Organizational Psychology

Provider of Florida CJBAT Program to approximately 30 FL law enforcement and correctional academies since 2001

Maintain a research and development function devoted to validating the CJBAT (on-going) and continually improving the computer-based test administration system

CJBAT Test Objectives

Assess core basic abilities as defined by FDLE

Provide an easily administered testing program

More rigorously screen abilities to ensure requisite ability levels

Establish compelling test validity evidence

CJBAT assesses the 8 mandated abilities using 120 questions covering 8 ability areas

CJBAT is available in paper and computer-based formats (with strong focus on customer service)

Careful research was done to establish an appropriate cut-off score that screens out unqualified candidates

Research demonstrates a strong relationship between CJBAT and academy/SOCE success

CJBAT Validation 2 criterion-related validation studies demonstrating the

relationship between the CJBAT and important criteria CJBAT correlated with academy performance (final

academy score) Data collected from Broward Sheriff, FHP, George Stone,

Gulf Coast, Lake Tech, Manatee Tech and Pinellas Sheriff CJBAT correlated with state certification scores (SOCE)

Data collected from all academies using CJBAT

General Guidelines for Interpreting Validity Coefficients (US Dept. of Labor)

Validity Value Interpretation

above .35 very beneficial

.21 - .35 likely to be useful

.11 - .20 depends on circumstances

below .11 unlikely to be useful

CJBAT Wrap-Up CJBAT is screening candidates

effectively (identifying a sizable subset of the sample that does not possess necessary abilities)

Academy and SOCE validation studies demonstrate that test is HIGHLY predictive of success in the academy and on SOCE

We are quite confident in the CJBAT’s defensibility based on its high validity levels

I/O Solutions is interested in continuing to learn from our clients how the CJBAT is functioning locally
