While teachers do generally receive raises, the amount and frequency of those raises can vary significantly depending on a variety of factors. Typically, schools do not offer an increase in teacher salary based on performance. In many cases, teachers may receive annual raises based on their level of experience and education. Some school districts also offer salary increases for teachers who obtain additional degrees or certifications, or who have been with the district for a certain number of years. Some teachers may receive bonuses or other incentives for meeting certain performance goals or working in high-need areas such as special education or STEM fields.
