All NEIU teacher candidates are required to have a negative tuberculosis skin test (a Mantoux) before entering any school. In accordance with the Illinois School Code (105 ILCS 5/24-5), all school boards require employees, and clinical students and student teachers, to provide evidence of freedom from communicable disease, including tuberculosis. Such evidence shall consist of a tuberculin skin test (NEIU Health Services requires Mantroux) and, if appropriate, a chest x-ray.

The TB test may be obtained in the NEIU Health Services Office at no cost or from a health provider outside NEIU. Those tested outside of NEIU must present their TB test results to the NEIU Health Services Office and receive a Tuberculosis Test Report Form. The teacher candidate then brings this form to the CEST Office.
