Core Selective Evaluation Process

About C-SEP

C-SEP (Core-Selective Evaluation Process) is an efficient and comprehensive approach to identify students with Specific Learning Disability (SLD) by determining a pattern of strengths and weaknesses using the core tests of the Woodcock-Johnson (WJ) IV, Wechsler or Kaufman Batteries with additional "selective" testing conducted as needed. Each assessment contains a "core" set of tests that provides a representative survey of abilities measured by the battery. Examiners can selectively administer additional tests to provide greater breadth of measurement in an area of cognition or linguistic competency or in a domain of achievement.
