During ACT registration you enter a high school code so your scores reach the right school, and you search for a test center by location— then double-check both on your admission ticket before test day. Getting either wrong can delay score reporting or send you to the wrong building. If you are still setting up your registration, start with how to register for the ACT.
High school codes and score reporting
Your registration fee includes a score report sent to your high school. You enter your school's four-digit high school code during signup so ACT knows where to send it. If you are unsure of the code, ask your counselor—they handle ACT logistics every year. Entering the wrong code can mean your school never receives your scores automatically.
Homeschooled students
If you are homeschooled, use high school code 969-999 during registration. That tells ACT to skip automatic school reporting. You still get your scores directly and can send them to colleges yourself. Full details are in how to register for the ACT as a homeschooled student.
Finding a test center
MyACT lets you search test centers by city, state, or zip code and shows which locations have seats for your date and format. Popular centers fill up fast, so register early for the best options near home. For how to weigh distance, format, and familiarity, read where you should take the ACT.
Verify everything on your admission ticket
Once your photo is approved, print your admission ticket from MyACT and confirm the test center name, address, date, and reporting time. If anything looks wrong, fix it through MyACT before test day—or contact ACT support if the change deadline has not passed. Showing up at the wrong center is an easy mistake to avoid with a two-minute check.
The bottom line
Your high school code and test center choice are small fields in registration with big consequences. Enter the correct school code, pick a center that fits your logistics, and verify both on your admission ticket. Two minutes of checking saves a lot of stress on test morning.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
