…Remind’s features have proved especially popular in low-income districts where parent engagement is a key issue for teachers and parents’ sometimes erratic work schedules can make it difficult to get in touch by phone. – Buzzfeed

Once a teacher starts to use the tool it tends to spread through the rest of the school like wildfire. Domonique Roberts a history teacher at University High School in Newark N.J. has been using Remind to communicate better with parents. 'I have been messaging one student’s mom telling her when he’s not doing homework or if he fell asleep in class today' Roberts says. 'She’s on top of it and his grade improved by two letter grades from the first marking period to the second just by keeping up with her.' – Fast Company
