Substitute Teaching Improvement Act - Authorizes the Secretary of Education to award competitive demonstration grants to high-need local educational agencies (LEAs) or partnerships between such LEAs and institutions of higher education or nonprofit education organizations for the establishment of comprehensive training programs to increase the effectiveness of substitute teaching.
Requires LEAs to use such grants to: (1) train substitute teachers; (2) train principals and permanent teachers in effectively integrating substitute teachers into school operations; (3) develop a resource kit for substitute teachers; and (4) collect data on substitute teachers and practices for managing substitute teachers in participating districts.
Directs the Secretary to commission an independent evaluation of the prevalence of substitute teaching and current state and local efforts to improve its effectiveness.
