What the NCED Exam Covers
ABNED's certification examination tests knowledge across the full psychoeducational evaluation process. Candidates must demonstrate mastery of cognitive assessment using tools such as the WISC-5 and WJ-IV, as well as academic achievement testing to measure reading, writing, and mathematics performance relative to same-age or same-grade peers.
The exam also addresses adaptive behavior assessment with instruments like the Vineland-3, social-emotional evaluation using the BASC-3, and eligibility determination across all 13 IDEA disability categories — including Specific Learning Disability (SLD), Intellectual Disability (ID), Emotional Behavioral Disorder (EBD), Autism Spectrum Disorder, and Other Health Impairment (OHI).
Strong knowledge of RTI/MTSS frameworks, report writing standards, and the diagnostician's collaborative role on the IEP team is essential. Ethical obligations under IDEA, Section 504, and professional codes of conduct are tested throughout.
