Licensure for Substitute Teachers

Research finds that teacher absences negatively affect student achievement and growth.^[1] While some of this is attributable to the disruption of regular classroom practices and instruction,^[2] it may also be attributable to substitute teacher quality. The gap in instructional quality and daily productivity when a regular teacher is replaced by a substitute teacher is significant.^[3] However, absences covered by substitutes licensed by the state are not as detrimental to student achievement as those covered by non-licensed substitutes.^[4] Some research hypothesizes that the low-skill level and mobility of substitute teachers may contribute to the reduction in instructional focus and quality and that even when substitute teachers are good instructors, they may be unable to effectively implement a teacher of record's long-term instructional strategies.^[5] Parents, teachers, principals, and students have concerns about substitute teachers' quality and qualifications.^[6] States should maintain rigorous standards for substitute teacher quality and accountability for all substitutes, but especially for long-term substitutes who are expected to stand in for teachers for long stretches of time.
