Middle School Basketball Rules: Quarters, Ball and State Changes

Middle school basketball rules: who writes them, quarter length, ball size, shot clock and running clock by state, and the high school rules middle schoolers play.

Middle school basketball has no national rulebook, so this page explains how state associations and leagues set the rules, shows how three states differ on quarters, the ball, the shot clock and the running clock, and lists the high school rules middle school games under NFHS rules use.

Middle school basketball rules are not written in one national book. School games below ninth grade are run by each state's high school association or by a league, and the three state documents on this page all start from the National Federation (NFHS) high school rules with a few changes of their own. That is why the answers to the common questions, how long a quarter is, which ball to use, whether there is a shot clock, change from state to state. This page shows what the official documents say, where three states differ, and the high school rules a middle school player meets for the first time. For the rules of your own games, check your state association and your league. Coaching a middle school team, from practice plans to parents, is on middle school basketball coaching.

Find the document that runs your games before the season: your state association's middle school rules, or your league's rule sheet. Quarter length, the ball, the shot clock and the running clock are all set there, and they are not the same in every state.

Who Writes Middle School Basketball Rules

The pattern in the state documents is the same. The state adopts the NFHS rules for school games and then lists its own changes. West Virginia's regulation says NFHS rules are the official rules for all school competition unless the state commission changes them, and the same rules apply to middle schools with the listed adaptations. Rhode Island's middle school handbook says games are played under NFHS rules except for the committee's special rulings. Delaware's 2017-18 adoption list, the latest this page could confirm, named the NFHS rules the state adopted or changed, and some of those changes covered middle school games too. Check your state association for the current list.

Rules marked 2017-18 come from that year's NFHS book and may have changed. Check your state association. Leagues outside school sports, such as recreation leagues, use their own rule sheets. The levels compared side by side, high school, college, NBA and FIBA, are on basketball rules and regulations.

How Three States Set Their Middle School Rules

Rule	West Virginia	Rhode Island (2026-27)	Delaware (2017-18 adoption list)
Base rules	NFHS, with state adaptations	NFHS, with committee rulings	NFHS, with listed adoptions
Quarter length	Six minutes for teams that combine 7th and 8th graders	Four 8-minute quarters, 5-minute overtimes until there is a winner	Not listed in the adoptions
Shot clock	Not listed	None	Not listed
Running clock	Not listed	Once a team leads by 30 in the 4th quarter, stopping only for free throws and time-outs	At 35 points at the end of the 3rd or any time in the 4th, back to normal if the lead falls to 25, middle school through varsity
Ball for boys	Not listed	Not listed	The boys' high school ball
Game limits	20 games plus up to three in a conference or county tournament, 120 quarters a season and six a day per player, no state tournament	14 regular-season games, then playoffs	Not listed

Rhode Island also allows a "fifth quarter" if both schools agree before the game. The score after the fourth quarter is the official score, and the coaches and administrators supervise the extra quarter. "Not listed" means the state's document does not set that rule, so the NFHS rule or another state rule may apply. The Delaware column is from 2017-18 and may have changed. Your own state may differ on every line.

How Long Are Middle School Basketball Quarters?

Six or eight minutes, depending on the state. The 2017-18 NFHS book (Rule 5-5-2) set six-minute quarters for games involving only students below ninth grade, and allowed eight-minute quarters for teams that combine ninth graders with eighth or seventh graders. That text is from 2017-18 and may have changed. High school games are four eight-minute quarters. West Virginia matches the six-minute rule for its combined 7th and 8th grade teams. Rhode Island plays four eight-minute quarters at middle school. Check your state association for the current rule. Halftime length by level is on how long is basketball halftime.

What Size Ball Do Middle Schools Use?

For boys, it has been the state's choice. The 2017-18 NFHS book allowed two legal balls, the boys' high school ball and the girls' high school ball, and a note to Rule 1-12-1 let each state association adopt either one for boys' junior high games. That is the most recent NFHS text this page could confirm, so the rule may have changed. Delaware's 2017-18 adoption list says the state had not acted on that note, so boys' middle school games used the boys' high school ball. In the 2017-18 book the boys' ball was 29½ to 30 inches around and the girls' ball 28½ to 29 inches. Girls' middle school games were not covered by the note. Check your state association for the ball it uses now. The ball sizes by age are on basketball sizes.

High School Rules Middle Schoolers Play

Where a state plays NFHS rules, these are the high school rules a middle school player is most likely to meet for the first time. Each comes from an official NFHS document or from the NCAA's published chart of NFHS and college differences. Check your state association for any change it has made.

Bonus. Since 2023-24, two free throws for a common foul starting with a team's fifth foul in a quarter. There is no one-and-one, and team fouls reset each quarter.
Three seconds. A player is out of the lane only when both feet are on the floor outside it. More on the 3 seconds rule.
Ten seconds. A team has 10 seconds to get the ball out of its backcourt. The count starts when a player controls the ball and resets on a new throw-in. More on the 10 second rule.
The division line. The line is part of the backcourt. A player with the ball in the frontcourt who steps on it has committed a backcourt violation. More on backcourt violations.
Free throws. Players in the marked lane spaces may move in when the shooter releases the ball, and they may not enter the semicircle until the ball touches the ring. More on basketball free throw rules.
Shot clock. A 35-second shot clock only where the state has adopted one. Rhode Island's middle school games have none. More on basketball shot clock rules.
Timeouts. Three 60-second and two 30-second timeouts in high school games. More on basketball timeout rules.

The division line. 1's team attacks the bottom basket. 1 has the ball in the frontcourt and puts a foot on the division line. Under the high school book the line is part of the backcourt, so that is a backcourt violation.

Ten seconds. 2 inbounds to 1 in the backcourt. Under the high school book the count starts when 1 controls the ball, and he has 10 seconds to get it across the division line.

Questions Coaches Ask

Do middle schools use high school basketball rules?

In West Virginia, Rhode Island and Delaware (going by its 2017-18 list), yes: each adopts the NFHS high school rules and then lists its own middle school changes, such as quarter length, the ball or a running clock. Check your state association and your league.

How long are quarters in middle school basketball?

Six or eight minutes, set by the state. The 2017-18 NFHS book, the latest this page could confirm, set six-minute quarters for games involving only students below ninth grade. West Virginia still uses six minutes for combined 7th and 8th grade teams, and Rhode Island plays eight. Check your state association.

Is there a shot clock in middle school basketball?

It depends on the state. A shot clock in high school is a state choice, and Rhode Island's middle school games are played with none. Check your state association.

What size basketball is used in middle school?

It depends on your state. The 2017-18 NFHS book let each state choose the boys' or the girls' high school ball for boys' junior high games, and that may have changed since. Delaware's 2017-18 list kept boys on the boys' high school ball. Check your state association.

Is there a mercy rule in middle school basketball?

Some states use a running clock. Rhode Island starts it when a team leads by 30 in the fourth quarter, and Delaware's 2017-18 list at 35 points at the end of the third quarter or in the fourth. Check your state association.
