Psychological Testing
Comprehensive psychological evaluations for diagnostic clarity, treatment planning, or answering specific clinical questions about how someone thinks, learns, or functions.
Structured assessment
What Psychological Testing Is
Psychological testing, also called psychological assessment or psychological evaluation, is a structured, multi-session process that combines clinical interview, behavioral observation, and standardized assessments to answer a specific diagnostic or functional question. It is most commonly used to evaluate ADHD, learning differences, autism spectrum presentations, cognitive functioning, and personality structure, or to clarify a diagnostic picture when initial impressions have been unclear.
Unlike a single intake conversation, a full evaluation draws on validated instruments selected to match the referral question, with results interpreted by a licensed psychologist. The deliverable is a written clinical report summarizing findings, diagnostic impressions when the data supports them, and concrete recommendations for treatment, school accommodations, workplace adjustments, or other supports.
At Thrive Psychological Services, our licensed psychologists conduct evaluations for children, adolescents, and adults across California, with most testing sessions held in-person at our offices in the Inland Empire. With your consent, we coordinate findings with referring providers so the results actually inform the next step in your care. Insurance coverage for psychological testing varies by plan and referral question; we verify benefits and discuss out-of-pocket options before the intake appointment.

Evaluation, insight, and answers
Gaining Diagnostic Clarity
Most evaluations begin with a specific question that needs a clear, evidence-based answer. These are the referral questions we work with most often.
ADHD Evaluation
Comprehensive assessment to clarify whether ADHD is present, often when symptoms overlap with anxiety, depression, or learning differences. Useful for adolescents and adults seeking a clear answer for the first time.
Learning Differences
Assessment for dyslexia, dyscalculia, reading or writing disorders, and other learning-based challenges affecting school or work performance. Reports support school accommodations and workplace adjustments.
Autism Spectrum Evaluation
Diagnostic evaluation for adolescents and adults, often after years of feeling misunderstood by other frameworks. Includes structured assessments and a clear written report with treatment recommendations.
Cognitive Functioning
Evaluation of memory, attention, executive function, and processing speed when changes in functioning need a clinical answer. Used to clarify whether what you're noticing reflects a clinical condition or normal variation.

Frequently Asked Questions
How long does a full evaluation take?
Most evaluations involve 3-6 total appointments across 2-4 weeks: intake, testing sessions, report writing, and feedback. The exact timeline depends on what we are evaluating and your scheduling.
Will my insurance cover testing?
Sometimes, depending on the referral question, the specific assessments used, and your plan’s coverage of psychological testing. We will verify benefits before the intake and discuss out-of-pocket options if testing is not fully covered.
What do I get at the end?
A written clinical report (typically 8–15 pages) summarizing findings, diagnostic impressions, and concrete recommendations for treatment, school accommodations, workplace adjustments, or other supports. You also get a feedback session where we walk through the report in plain language.
Can testing diagnose ADHD or autism?
Testing can contribute meaningfully to those diagnostic questions, but diagnoses are clinical judgments made by integrating testing data with history and observation. Our reports include clear diagnostic impressions when the data supports them.
