Core Course
A core course is an NCAA-approved academic class in English, math, science, social science, foreign language, or comparative religion/philosophy that counts toward eligibility. Division I requires 16 core-course credits; the specific mix and GPA threshold determine whether an athlete qualifies.
Not every high school class counts. The NCAA maintains a list of approved courses for each high school — athletes should verify their schedule against that list early, ideally starting freshman year, so they don't arrive at senior year short of the required credits.
Core-course GPA is calculated only from these approved classes, not from a student's overall GPA. This means an athlete with a strong overall GPA can still fall short of eligibility if too many of their credits come from non-core electives.
Division I requires 16 core courses in a specific distribution: four years of English, three years of math (Algebra 1 or higher), two years of natural/physical science, two years of social science, one additional year of English/math/science, and four additional years of any of the above or foreign language. Division II also requires 16 core courses but with a slightly different distribution.
Ten of the 16 Division I core courses must be completed before the start of senior year, and seven of those ten must be in English, math, or science. This is why waiting until senior year to fix academic gaps often does not work — the window has already closed.
Online and credit-recovery courses may or may not count as core courses depending on whether they appear on the high school's approved list and meet NCAA review standards. Families relying on non-traditional credits should confirm eligibility with the Eligibility Center before counting on them.
