In the United States, dual enrollment (DE), also called concurrent enrollment, programs allow students to be enrolled in two separate, academically related institutions. Generally, it refers to high school students taking college or university courses.

Gross Enrolment Ratio (GER) or Gross Enrolment Index (GEI) is a statistical measure used in the education sector, and formerly by the UN in its Education Index, to determine the number of students enrolled in school at several different grade levels (like elementary, middle school and high school), and use it to show the ratio of the number of students who live in that country to those who qualify for the particular grade level. The United Nations Educational, Scientific and Cultural Organization (UNESCO), describes "Gross Enrolment Ratio" as the total enrolment within a country "in a specific level of education, regardless of age, expressed as a percentage of the population in the official age group corresponding to this level of education".

Strategic Enrollment Management [SEM] is a crucial element of planning for new growth at a university or college as it concerns both academic program growth and facilities needs. Emerging as a response to fluctuations in student markets and increasing pressure on recruitment strategies in higher education, SEM focuses on achieving student success throughout their entire life cycle with an institution while increasing enrollment numbers and stabilizing institutional revenues.
