Independent School Admissions Evaluations

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

The Stixrud Group, LLC has partnered with Mid-Atlantic Clinical Services, Inc to provide an abbreviated school admissions evaluation for children required to submit a cognitive or academic test as part of the application process for independent, private schools in the Washington, D.C. area.

Having conducted neuropsychological evaluations since 2001, Carol Mannix, M.A., President of Mid-Atlantic Clinical Services, works under the supervision of Lisa Martin, Ph.D., and has the expertise to ensure that the assessment process is a positive one for clients of all ages and abilities.  To accommodate the busy schedules of parents and the time constraints that arise during the private school application process, we provide flexible testing times on weekdays and weekends and an expedited report delivered to families within one week of the evaluation.



To schedule an appointment for Admissions Testing, please contact Carol Mannix at 301-672-3649 or email her at carol@mannixmail.com. Once your request has been received we will contact you to arrange your specific appointment time. The length of your appointment may vary depending on which tests are 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 information before you arrive for your appointment. It is recommended that children (especially under the age of 10) be tested in the morning.

Payment is due in full at the time of the appointment.
