PTA stands for Parent-Teacher Association, a body of a school's parents and teachers that meets to support the school, raise concerns and discuss students' progress and welfare. A PTA meeting is the regular occasion where a teacher and a parent talk about a specific child. Many schools run a PTA alongside, or as part of, their formal School Management Committee.

Most parent contact around a PTA — meeting reminders, notices and follow-ups — happens on WhatsApp and SMS now. RaivatEdu sends those from the student record so the message history stays on the child's timeline, without needing parents to install anything.
