School Admission Testing

The Stixrud Group, LLC is pleased to offer School Admissions Testing!

Admissions testing is available for children and adolescents who are required to complete an individually administered cognitive or achievement test as part of the school admission application process. Carol Mannix, M.A., under the supervision of licensed psychologist Susan Gerson, Ph.D., is conducting these evaluations. With over 15 years of experience completing neuropsychological evaluations with The Stixrud Group, Carol has a proven track record of establishing excellent rapport with children of all ages and abilities. We are confident that your child will have a positive testing experience in our office. We are aware of the time constraints that arise during the application process, and we offer flexible weekend and weekday testing times, as well as competitive pricing and an expedited report.

Administration Procedure:

The length of your appointment may vary depending on which test is required, although a minimum of one hour in our office is to be expected. It is the responsibility of the family to know which test your child needs for the particular school(s) to which you are applying. Please confirm this before you arrive to your appointment. It is recommended that children, especially under the age of 8, be tested in the morning.
