For our next PTC-SC  event, we will be hosting Dr. Calvin C. (Cal) Hoffman, who will present the results of the Criterion-Related Validation of the Deputy Sheriff Trainee Written Test and Physical Ability Test Battery, conducted at the Los Angeles Count Sheriff’s Department.

This presentation covers highlights of two large sample criterion-related validation studies conducted at Los Angeles County Sheriff’s Department. Using archival data from 10 academy training classes, LASD staff members completed a criterion related validation study of an internally-developed cognitive ability test in use for over 10 years.
