What An Evaluation Includes

I provide consultations, school observations, and evaluations, each scoped to the specific questions a family brings. Evaluations range from a focused assessment, such as cognitive testing for school admissions, to a more comprehensive evaluation covering the areas outlined here, with treatment recommendations where appropriate.

This is also a practice built around families with real deadlines. I know the cost of waiting when an admissions deadline or an important decision is on the line. Expedited turnaround, along with evening and weekend appointments, is available at an adjusted rate when scope allows.

Testing is conducted in person, on a limited and scheduled basis. Reach out to discuss current availability and dates.

What I evaluate
  • Giftedness identification
  • School and program admissions
  • Grade acceleration
  • Twice-exceptional (2e) profiles
  • ADHD and attention
  • Executive functioning (organization, planning, focus)
  • Social and emotional functioning
How Fees Work

Billed By The Hour

Testing is billed at an hourly rate rather than a flat package price, because every child's evaluation takes a different amount of time depending on the referral question.

A brief initial phone consultation is free of charge. I use it to understand what you are looking for, and to discuss the rate and an estimated number of hours. That estimate is confirmed and paid in advance of your first appointment, so there are no surprises, and the fee is never contingent on the results.

Questions

What People Ask Before We Begin

What does psychological testing involve, and who is it for?

Clear, credible answers about a child's cognitive, learning, and emotional profile: giftedness, admissions, acceleration, twice-exceptional questions, ADHD, executive functioning, and psychological evaluation (social and emotional functioning with treatment recommendations).

What actually happens during testing? Will it feel like a test my child can fail?

There is no way to fail. Testing is a series of structured activities, questions, puzzles, and short tasks appropriate to your child's age, given one-on-one in a calm setting. I take time to build rapport first, so your child understands what to expect and feels at ease. The goal is an honest, complete picture of how your child thinks and learns, not a pass-or-fail outcome.

What does the evaluation process actually involve?

It depends on the scope. A focused assessment, like cognitive testing for a school admissions deadline, can often be completed in a single appointment, followed by a written report of your child's scores, since most schools require documented results rather than a letter alone. A more comprehensive evaluation typically includes an initial parent meeting, two to four testing sessions with your child, a parent feedback meeting, and a full written report with recommendations. Where useful, that can also include a school observation, a review of prior records or assessments, and rating scales completed by parents or teachers.

What happens after testing is complete?

You receive a clear, written report explaining the findings in plain language, along with specific recommendations. We review it together so you understand what it means and how to use it, whether that is for a school accommodation or an admissions decision.

How is pricing structured?

Testing is billed hourly rather than as a flat package, since every evaluation takes a different amount of time. The rate and estimated hours are discussed during your free consultation, and confirmed and paid before your first appointment. Expedited and evening or weekend scheduling is available at an adjusted rate.

What if my child's evaluation needs more time than originally estimated?

Occasionally, additional hours are needed beyond the original estimate, for example, a school consultation or meeting, or an additional request from a parent. If that happens, I will always discuss it with you and confirm the added cost before any additional time is billed.

How quickly can I get results?

Expedited timelines are available when the assessment scope allows. Reach out to discuss options for your specific situation.

Where does testing happen?

Testing is in person in Los Altos, a convenient Silicon Valley location, on a limited and scheduled basis. Reach out to discuss current availability and dates.

Do you accept insurance?

No. This is a private-pay practice.
