Intensive English Programs Survey
IIE, with the assistance of two leading professional intensive English program (IEP) associations, English USA and University and College Intensive English Programs (UCIEP), annually collects national-level data on IEP enrollments in the United States, a known pathway toward enrollment in full degree programs. Programs that are not English USA or UCIEP members were also invited to participate in the survey.
Reporting institutions include university and college-affiliated programs, as well as independent entities that offer English language training. The Open Doors 2025 IEP survey reflects student enrollment during the 2024 calendar year (January 1 to December 31, 2024). Data elements in this survey include place of origin, program sponsorship, percentage of students intending to continue further (non-IEP) study in the United States, and program duration (18 hours or more, fewer than 18 hours). Both total student enrollment and total student-weeks (one student studying for one week) are captured. These two measures provide a more complete picture of IEP enrollments in the United States. Because they cover different populations, enrollment data from the IEP survey are not always congruent with IEP enrollment data from the International Student Census. Throughout the report, rates of change listed may have been controlled for changes in institutional reporting.
Beginning with Open Doors 2014, data imputation has been carried out to account for non-responding intensive English programs. The reporting programs and those for which data were imputed together account for 50 percent of all institutions that were surveyed. Beginning in Open Doors 2017, rates of change listed for place of origin may have been controlled for changes in institutional reporting. This calculation is based on institutional year over year reporting. (See Imputation and Estimation for more details).
