Normally in Indian Schools, they will ask atleast the Bachelors Degree for teaching. I hope even in Pakinstan School also they will ask for Bachelors Degree. But sometime they will look for previous experience only. They will conduct demo before appointment. If you do well in the Demo they can appoint you. Just send your CV to all the Schools in Doha thru e-mail. Just a try. May it will clik on.
