Most California teachers have the appropriate credentials and training to teach the subjects and students in their classes, but many do not, according to new statewide data on teacher assignments released Thursday.
While 83% of K-12 classes in the 2020-21 school year were taught by teachers credentialed to teach that course, 17% were taught by teachers who were not.
Teachers are required to have either a multiple-subject, single-subject or special education credential to teach, depending on the grade level and coursework, but an ongoing statewide teacher shortage has meant that most school districts have had to rely on teachers who are not fully prepared to teach at least some classes on their schedules. Often that has meant teachers working with various emergency-style permits or waivers.
“There is no question that well-qualified teachers are among the most important contributors to a student’s educational experience,” said State Board of Education President Linda Darling-Hammond. “California is committed to ensuring that every student has teachers who are well-prepared to teach challenging content to diverse learners in effective ways and are fully supported in their work. With this data, we can focus on measures to assist our educator workforce as they strive to provide high-quality teaching to all students, especially our most vulnerable students.”
The new Teacher Assignment Monitoring Outcome data is the state’s newest tool in its battle to end a long and enduring teacher shortage. It is expected to guide state and local leaders on how best to use resources to recruit and retain teachers and will inform California residents about teacher assignments in their local schools. It also allows California to finally meet federal Every Student Succeeds Act requirements.
“The release of the teacher data is a milestone achievement, years in the making,” said John Affeldt, managing attorney at Public Advocates, a public interest law firm. “We wish it had been here years ago but now the state will finally have data capturing the quality of the teaching force statewide down to the school level.”
