Hi Dear,
I am sharing latest update by harvard education i hope it will help you , as update on their site due to limitations caused by COVID-19, the GRE is optional for applicants to the online Ed.M. for fall 2020 enrolment. All applicants for enrolment in the 2021-2022 academic year are required to take the Graduate Record Examination (GRE) General Test. Doctor of Education Leadership (Ed.L.D.) applicants ONLY may choose to submit GMAT scores in lieu of GRE scores.
