Clear Answers for Orange County Families
When a child is struggling with reading, writing, math, attention, organization, behavior, or emotional concerns, families need more than general feedback. They need a clear explanation of what is happening and what support may help.
Evaluations examine the student’s learning profile and may include cognitive, academic, executive functioning, attention, adaptive, behavioral, and social-emotional areas.

Frequently Asked Questions
What type of evaluation should my child have?
A comprehensive psychoeducational evaluation is best when there are multiple concerns or unclear diagnoses. A learning differences evaluation is a better fit when concerns are mainly reading, writing, or math. An executive functioning and attention evaluation is appropriate when concerns involve focus, organization, follow-through, or self-regulation.
Do you evaluate for dyslexia?
Yes. The academic learning differences evaluation is designed to identify reading, writing, and math-based learning disabilities, including dyslexia, dysgraphia, and dyscalculia.
Do you offer GATE testing?
Yes. GATE and advanced learning assessments look at cognitive strengths, learning style, problem-solving, and advanced learning potential.
Can you provide an Independent Educational Evaluation?
Yes. IEE services include assessment, review of the district’s offer of FAPE, placement and services, written findings, and IEP meeting participation when included in the evaluation scope.
