The language acquisition process is different for every student, it takes approximately 12 years of study to reach advanced proficiency. It is also expected that the students will have mastered the specified district curriculum taught in this program and reach an advanced level on the A.C.T.F.L Proficiency Scale by high school graduation.

The ISA program is recognized by the Ministry of Education of Spain. The Ministry makes resources and programs available to ISA schools throughout the world to assist them in preparing the students to participate in international university programs. Students also have multiple opportunities to earn the Seal of Biliteracy.
