At our core, we all want to be recognized for the work we do. Students are no different. Even a simple piece of paper saying, "I see your good work" can go a long way. That's exactly what a Certificate of Achievement does.
Print off a certificate with your student's name on it and present it to students as a token of their achievement like reaching 500 LiveSchool points. At schools that write positive referrals, some print the certificate to award the student when the admin processes those referrals.
