Teacher and Nurse Support Act of 2005 - Amends the Higher Education Act of 1965 (HEA) to increase to a maximum of $17,500 the aggregate student loan obligation eligible for forgiveness or cancellation programs for teachers who serve full-time in certain elementary or secondary schools (which qualify based on enrollment of disadvantaged students).
Includes, under these HEA student loan forgiveness and cancellation programs, nurses who serve in a clinical setting or as a member of the nursing faculty at an accredited school of nursing.
Directs the Secretary of Education to repay such loan obligation in annual installments up to specified maximum amounts after each of five years of such service.
