Frequently Asked Questions
Common questions about Harker admissions testing, timing, costs, and what to expect on test day.
No. These assessments measure natural reasoning and thinking ability, not learned academic content, and the scoring already adjusts for your child's exact age. Your child competes against the same age group no matter the month, so testing later offers zero scoring benefit.
No. Waiting provides no advantage. Cognitive assessments use age based scoring, which compares your child only to other children born around the same date. Testing in September or December places your child in the same age group, so a few months makes no difference to the score.
As early as possible. Appointments for ages four and five fill the fastest because spots are limited and the testing has specialized requirements. A good rule is to book roughly four to six months before your school's application deadline, and even earlier for Transitional Kindergarten.
TK and kindergarten applicants need the earliest appointments because spots are highly limited and testing for the youngest children has specialized requirements. Demand peaks near the end of the year, when Thanksgiving and December holidays reduce the number of available testing days.
Waiting too long. Many parents assume an older child will perform better, but age based scoring means that is not true. The real risk is losing your appointment window, since year end demand and holiday closures cause some families to miss their deadlines entirely.
It is risky. Every December, families call seeking urgent appointments, but holiday closures and heavy demand mean some cannot secure a date in time. Even with weekend availability, a last minute slot is never guaranteed.
Harker requires either the WPPSI-IV or the WISC-V, and the right one depends on your child's age at the time of testing. The WPPSI-IV is used for ages four to seven years and seven months, and the WISC-V is used for ages six to sixteen. Transitional Kindergarten applicants always use the WPPSI-IV.
Your child must be at least four years old at the time of testing. Testing can begin as early as age four, which gives most families flexibility to schedule well before application deadlines.
Plan for about 90 minutes to two hours. The exact length depends on your child's age and pace, since Dr. Estupinian allows individual timing and breaks to keep your child comfortable throughout.
Results are typically ready within one to two business days. The assessment also includes a review of the results with Dr. Estupinian so you understand what the scores mean for your child.
Yes. Dr. Estupinian is an official Harker School preferred psychologist with more than a decade of experience assessing applicants for Harker admissions. She is also board certified in clinical psychology by the ABPP, a credential held by only a small fraction of clinical psychologists.
Yes. You are welcome to test for your own understanding without submitting results anywhere. Keep in mind that these cognitive tests cannot be retaken for a full year, so timing matters if you may want to apply to a school later in the same cycle.
A cognitive assessment measures how your child thinks, reasons, and processes information, while an achievement test measures what your child has already learned in school. These tests reflect natural ability rather than memorized academic content, which is why preparation and tutoring do not change the result.
Both tests evaluate five core areas of thinking: verbal comprehension, visual spatial processing, fluid reasoning, working memory, and processing speed. Together these give a complete picture of how your child learns and solves problems.
Dr. Estupinian always administers all required subtests, never an abbreviated version. She also sequences the activities in a child friendly order and uses breaks to keep your child engaged and at ease.
Look for a doctoral level psychologist with state licensure, specific training in the WPPSI-IV and WISC-V, and a high volume of completed assessments. For Harker specifically, preferred provider status and direct experience with the school's requirements matter most.
