This is the test my coworker is taking I know nothing about it hopefully someone else on here does . We have EL coursework embedded in our credential . However , I reread and saw that you ' re certified in ESL so I bet you won ' t even have to take the test . Hopefully you ' re fine and they count what you already have ! The 30 post bacc units isn ' t something you have to do , just something to be aware of . It ' s the reason our salary scales will look different than what you might be used to . They ' re skewed for a population of teachers that has more units in general . I subbed before I was credentialed , while I was going through my program . It ' s called an emergency credential . To be honest , I don ' t really remember what it requires . To the best of my memory , it ' s a bachelor ' s , a basic skills test CBEST for us , but I ' m sure you ' ve taken an equivalent to be certified in TX , and fingerprinting with the county office of ed where you want to sub . California ' s a little confusing . There are a lot of hoops . I would see if you can find a contact person on the CTC website to email . Texas is a huge state this can ' t be the first time someone has moved from there to CA to teach ! They ' d be able to give you more specifics . One thing to know , since you have elementary certification I have heard that TX is really big into departmentalization at the elementary level . That is super rare here . At most , it might take place in 5 th or 6 th grade 6 th is sometimes elementary here , but even that isn ' t super common . Almost everything in elementary is self contained .
