The only thing parents want for their child is to have a good and happy education. So, when you are promoting your educational institute, make sure to mention the facilities you offer, the kind of activities the institute provides, the quality of education you provide. Also, make sure to show the kind of safe, happy environment the institute provides. (anti-bullying and anti-ragging). Show off your institute's reputation, which not only attracts the parents but also convinces them that their kid should study in your institute.
