Hello, I would like to start a thread for methods for already certified teachers to gain additional certifications in content areas. WGU has the most well known where you can take a masters in a content area to get certified to teach a second subject. (math, physics, biology, chemistry) Fresno Pacific and University of La Verne offer graduate PD courses in a variety of subjects. I'm not sure if these would be acceptable for an additional certification. I am personally looking to add English certification. I am currently certified for social studies and TESOL. Please share any additional programs. No need to add endorsement programs. They are fairly common.
