Frequently Asked Questions
What if my child misses the cutoff by a few weeks?
You'll typically wait a full year. Some parents choose to 'redshirt' — deliberately hold back a child born just before the cutoff — giving them an extra year of development. Research on outcomes is mixed.
Can I start my child early?
Some districts allow early entrance testing for gifted children. Most states have limited flexibility. Check with your local school district.
