HS teachers for cs don't have grad school requirements, at least in the us. Also in the US there is a great shortage of experienced people for teaching jobs in the schools that are tech oriented. They can give you a temporary permission to teach, even if you don't have your teaching credential. If you have at least a BS/BA in some field with exp in the area, they'd probably take you in a second. They also do this for math and various science related fields.
