My son studied from eighth to twelfth in Hyderabad. Will he be considered as local?

Yes, your son will be considered local in Hyderabad if he has studied grades 8-12 in Hyderabad, which is in the state of Telangana. The criteria for the students to be considered local for Telangana admissions are that they should have studied in the state for four consecutive years to sit in the entrance exam like TS EAMCET. As your son has completed grades 8-12 in Hyderabad, he meets the criteria.
