How many letters of recommendation do I need? Although it can vary, generally, you will be asked for three letters. We recommend that you send only the number of letters requested. Admissions committees do not have enough time to read extra credential.
References may also be required of companies seeking to win contracts, particularly in the fields of engineering, consultancy, industry and construction, and with regard to public procurement and tenders.
