The APT assesses candidates on the Illinois Professional Teaching Standards and the language arts and technology standards for all teachers.
For example:
An individual who holds an Elementary K-9 certificate and applies for a Secondary 6-12 certificate on or after October 1, 2003, will be required to take the APT-Secondary or the APT-Special because the certificate held does not cover the grade range of the new certificate.
An individual who holds a Special K-12 certificate and applies for an Elementary certificate on or after October 1, 2003 will not be required to take the APT because the certificate held does cover the grade range of the new certificate.
There are 4 versions of the test: Early Childhood, Elementary, Secondary, & Special. The type of certificate sought determines which version of the test is required.
| Certificate Sought | Level of APT Required |
| Early Childhood (Birth to Grade 3) | APT-Early Childhood |
| Elementary (K-9) | APT-Elementary or APT-Special |
| Secondary (6-12) | APT-Secondary or APT-Special |
| Special (K-12) or (P-21) | APT-Special |
The APT test framework, which describes the content covered on the test, test registration information, and the study guide (available late May) may be found at: www.icts.nesinc.com.
Note: The APT requirement is in addition to the requirement for passing the basic skills and subject-matter knowledge tests.
