The IDP full form in IELTS is International Development Program. This program is not directly related to the IELTS test itself but refers to a broader initiative by IDP Education, a prominent organization that offers IELTS testing services. The International Development Program consists of a number of initiatives that support global education and cross-border student and professional mobility. These initiatives may involve helping those who want to study or work overseas, supplying educational resources, and helping people with the IELTS test, which is frequently necessary for people who want to pursue further education or a job abroad.
