Organizations for Educators
SIGCSE SIGCSE is the Special Interest Group for CS Educators within the ACM. Membership is inexpensive. SIGCSE and associated organizations hold many conferences each year.
APCS The College Board has a special interest group for Advanced Placement CS teachers. APCS has an annual conference. The lists are managed by the APCS Community. Note that there are two different groups here, one for APCS A and one for APCS Principles. These are the two courses for which they provide testing.
CSTA This group is primarily for Educators at Secondary level and below, though many college faculty also belong. CSTA has an annual conference.
