D1, D2, D3, NAIA and junior college compared

US college basketball has five main levels: NCAA Division I, II and III, the NAIA, and junior college. They differ in how many scholarships they give, what grades you need to get in, and how long you can play.

Here they are side by side, then one level at a time, written for Australian players and parents.

The five levels side by side

	NCAA Division I	NCAA Division II	NCAA Division III	NAIA	Junior college (NJCAA)
Colleges (roughly)	360	300	420	250	500
Athletic scholarships	Yes	Yes, usually partial	No	Yes, usually partial	Division I and II yes, Division III no

College counts are from the NCAA (September 2025), the NAIA and the NJCAA, and change each year.

NCAA Division I

Division I is the top level, with about 360 colleges. It includes the big conferences you see on TV.

• Scholarships. Under the 2025 House settlement, colleges that opted in no longer have a scholarship limit. They have a roster limit of 15 for men's and women's basketball and can give a scholarship to every player on it. Some colleges also share revenue with players.
• Academics. 16 core courses from Year 9 to Year 12 and a core GPA of at least 2.3. For 2026–27, students with 13 or more core courses and a core GPA of 2.8 or higher get an automatic waiver.
• Eligibility. Five seasons in a five year window, starting at your first full time enrolment at any college, or the college year after you turn 19, whichever comes first. See NCAA eligibility for Australian basketball players.

NCAA Division II

Division II has about 300 colleges, many of them smaller state universities.

• Scholarships. Each basketball team can give up to 10 full scholarships' worth of aid, and most colleges split this into partial scholarships across the roster. Athletic aid can be combined with academic scholarships and other aid.
• Academics. 16 core courses and a core GPA of at least 2.2. The same 13 course, 2.8 waiver applies for 2026–27.
• Eligibility. Division II adopted the same five year rule as Division I in August 2026.

NCAA Division III

Division III is the largest NCAA division, with about 420 colleges. Many are small private colleges with strong academics.

• Scholarships. None for sport. The NCAA says about 75 percent of Division III athletes get merit or need based aid instead.
• Academics. Each college sets its own admission standards. International students still need their athletics eligibility certified by the NCAA Eligibility Center.
• Eligibility. Currently four seasons. A proposal to move Division III to a five year rule has been put forward for the 2027 NCAA Convention.

NAIA

The NAIA is a separate association of about 250 smaller colleges.

• Scholarships. Each basketball team can give up to 8 scholarships' worth of aid, which colleges can split however they like. Some academic aid doesn't count towards the limit.
• Academics. You qualify as a first year with a GPA of 2.3, or two of these three: a GPA of 2.0, the top half of your graduating class, or an ACT of 18 or SAT of 970. The NAIA uses an overall GPA from all your subjects, not just core ones. International students need an InCred evaluation, and should send everything at least two months before starting. See NAIA basketball for Australians.
• Eligibility. Four seasons, finished within ten semesters.

Junior college

Junior colleges (also called JUCO or community colleges) are two year colleges. Most play in the NJCAA, which has about 500 members across three divisions.

• Scholarships. NJCAA Division I colleges can give full scholarships (tuition, fees, room and board, books). Division II scholarships cover tuition, fees and books only. Division III gives no athletic scholarships.
• Academics. You need to have finished school. There's no entry GPA. Once you're there, you need to pass your classes to stay eligible.
• Eligibility. Two seasons per sport. Under the NCAA rule, junior college enrolment also starts your NCAA five year window, so plan where you'll go next. See junior college basketball for Australians.

Players use junior college to get stronger, lift their grades, or earn a move to Division I, Division II or the NAIA after one or two seasons.

Which one fits

Start with three questions.

How good are you right now? Be honest about where you'd get minutes. A coach at the right level will want you to play, not sit. Ask your club or state coach where they think you fit.

What do your grades look like? If your core GPA is below what Division I or II needs, the NAIA or junior college may be the way in. Use the GPA calculator for an estimate, and check which subjects count in your state.

What can your family pay? Full scholarships are most common at Division I and NJCAA Division I. At Division II and the NAIA, ask each college what the scholarship covers and what's left to pay. At Division III, ask about academic and need based aid. See what a basketball scholarship covers.

A rough guide:

• Division I if you're already playing at the top of your age group nationally and your grades meet the rules.
• Division II or the NAIA if you're a strong state level player and want to play big minutes, or want a smaller college.
• Division III if academics come first and your family can cover costs with academic or need based aid.
• Junior college if your grades or your game need another year or two, or if you want a pathway to a four year college.

Many players move between levels during college. Under the five year rule, the clock keeps running when you transfer, so every move needs to be planned.

This is general guidance

Rules change most years, and the NCAA, the NAIA and the NJCAA make the official decisions. Ask each college's compliance office if you're unsure.
