A: If your child�s scores are very close, you may wish to have him/her take the tests the next time offered. Or the tests can be taken again in future years. Bear in mind the scores needed to qualify increase as the child�s grade increases.

Special instructions for 2, 3, 4, 5, or 6 grade students who will take the SCAT within the same year: Students may retake the SCAT at a later date to attempt to establish their eligibility. Students make take the SCAT up to two times per academic year. All requests for retests must be submitted by May 31. To retake the SCAT, submit a written request to CTY at:

SCAT Retest
CTY Talent Search
Johns Hopkins University
McAuley Hall
5801 Smith Ave
Baltimore, MD 21209

You can also fax your request to 410-735-6220, or email ctyretest@jhu.edu.

Include your child�s name, birth date, address, CTY student ID (if available), the name of the test you took (SCAT), and the date you took the test. A new SCAT registration bulletin will be mailed to you.
