Parents Teachers Meetings

When schools are planning to have parent-teacher meeting at school to dicsuss strudents learning progress, attendence and ther issues, school can use IVRS to invite parents to this meeting. school can request parents through IVRS voice call to participate in Parent-Teacher meeting.

Special Classes in School

In schools, for 10th students there will be regular special classess now. and its important to inform parents about special class timings. So that they will be aware about their children and it will help parents to send their children on early hours to school. Same information can send through IVRS voice calls to parents.

Progress Card

School intention is to send progress card to home is to make parents awarded about their children progress. Most of the time students will not show their Progress card to parents and they will make parents signature instead of parents. In this context school can send a voice call through IVRS to inform about progress card issued and request them to see the progress and to make signature.and also school can request parents to meet class teachers if students progress is not good.

Irregular and Slow learn Students

If students are not attending classes regularly, most of the time parents may not aware about it. If school inform parents about their children absents, then parents can enquire and observe their children. and also school can make communication to parents about their children poor learning progress. and here school can insist parents to focus on their children reading at home. School can make list of Irregular and Slow learn Students and can send voice calls to those parents through IVRS.
