A certificate extension or endorsement issued under CA-HQ is permitted only in the areas of English, mathematics, sciences, foreign languages, or social studies. Health and physical education areas may be added only for those teachers holding the correlative certificate.

This option may be particularly interesting to teachers who wish to extend or add to their certificates due to changes in school configurations within their districts. For example, a teacher who has been teaching 6th grade math with a K-4/P-5 certificate is allowed to do so in a P-6 school configuration. However, this assignment is “out-of-field” should the district change to a 6-8 middle school configuration. Likewise, those teachers currently holding high school certification may be interested in extending their grade range down to grade 5 via a CA-HQ.
