A credential is a state license required for teaching in K-12 public schools, issued by the Commission on Teacher Credentialing (CTC).
There are two science credentials: 1) Foundational-Level General Science which allows you to teach introductory (General, Life, or Physical) or integrated science (K-8) courses; and 2) Single Subject Science which allows for advanced courses in the designated subject area (Biological Science, Chemistry, Physics, Geosciences), and introductory or integrated science (K-12) courses.
Credentials are issued to applicants upon completion of an approved teacher preparation program. See many helpful tips at Find the Right Preparation Program
. Individuals with out-of-state credentials, teaching experience at regionally accredited private schools, or National Board Certification may apply directly to the CTC.
