About Psychoeducational IEEs
A Psychoeducational Independent Educational Evaluation (IEE) provides a clear and objective understanding of a student’s cognitive, academic, and emotional development. It identifies how a student learns, processes information, and responds to challenges — empowering families and educators to make informed educational decisions.
At Comprehensive Assessment Services (CAS), every psychoeducational IEE is led by Donald Ghrist, LEP (#2703), a licensed educational psychologist with over 25 years of experience. His evaluations bring insight, accuracy, and compassion to every case.
What a Psychoeducational IEE Measures
Psychoeducational evaluations provide a comprehensive look at how a child learns and functions. This includes assessing the brain-based skills that underlie academic success, such as attention, memory, processing speed, and reasoning.
🧠 Cognitive Abilities
Understanding a student’s intellectual strengths and weaknesses across reasoning, problem-solving, and processing skills.
📘 Academic Achievement
Measuring reading, writing, and math skills to identify learning differences or academic delays.
❤️ Social & Emotional Functioning
Assessing mood, behavior, and self-regulation that may impact learning and classroom performance.
🧩 Learning Profiles
Creating a holistic picture of how a student learns best — identifying areas for support and enrichment.
These evaluations are particularly valuable when identifying learning disabilities (such as dyslexia or ADHD), verifying eligibility for special education, or understanding behavioral concerns that affect school performance.
