That’s according to figures on the California Teachers Association’s website, which until August listed its membership as 325,000. The number is now 310,000.
For at least the last five years, the CTA has posted its membership as 325,000 and it is not clear over what period its membership has declined.
But the decline appears to be largely the result of the “disaffiliation” this past spring of the California Faculty Association from the CTA. The association represents faculty and other staff at the California State University system and had been affiliated with the CTA for decades and thus were automatically CTA members.
