Re: Good School In islamabad
I taught in the Montessori branch of Headstart in Islamabad about 6-7 yrs ago so I can vouch for that. it was a relatively new school back then, lots of emphasis on one-on-one instruction, 2-3 teachers to a classroom till class Prep (5 yr olds), disciplined classrooms but lots of fun activities too. Of course i don’t know if they have maintained that standard, so you can call for an appointment, do a tour and all that. good luck
