If you are planning to study in the US you will likely be required to take one or more of the common standardised tests for US college admission. You should check the admissions criteria of the college(s) you intend to apply to in order to determine which of the following test(s) you might need to take.
Fulbright New Zealand does not administer any US standardised tests, and cannot provide advice on standardised testing to the general public. Direct any questions about test registration and administration to the test company directly. If you have more detailed questions about a test, please contact Education USA.
