The substantial disruption test is the major standard developed by the U.S. Supreme Court in its seminal student speech K-12 decision Tinker v. Des Moines Independent Community School District (1969), to determine when public school officials may discipline students for their expression. It remains the leading test used in student-speech cases, including cases involving off-campus, online speech.

The substantial disruption test is the major standard developed by the U.S. Supreme Court in its seminal student speech K-12 decision Tinker v. Des Moines Independent Community School District (1969) meant to determine when public school officials may discipline students for their expression. It remains the leading test used in student-speech cases, including cases involving off-campus online speech.
Substantial disruption test developed in Tinker case
The Tinker case involved public school students in Iowa who wore black peace armbands to protest U.S. involvement in the Vietnam War, to support Robert Kennedy’s Christmas truce, and to mourn those who had died. School officials suspended the students under a hastily enacted no-black armband policy. They challenged their suspension in court.
Though the students lost in the lower courts, the U.S. Supreme Court reversed and ruled in favor of the students. The Court wrote: “Certainly where there is no finding and no showing that engaging in the forbidden conduct would materially and substantially interfere with the requirements of appropriate discipline in the operation of the school," the prohibition cannot be sustained. The Court concluded that wearing the armbands did not cause any significant disruptions at the schools.
Supreme Court adopted test for a Circuit Court case
The U.S. Supreme Court actually adopted the test from the 5th U.S. Circuit Court of Appeals in Burnside v. Byars (1966). In that case, the 5th Circuit ruled that public school officials violated the free-speech rights of several African-American female students who wore “Freedom Buttons” to school to protest voting discrimination. The 5th Circuit explained that school officials cannot punish students for the exercise of their First Amendment rights “where the exercise of such rights in the school buildings and schoolrooms do not materially and substantially interfere with the requirements of appropriate discipline in the operation of the school.”
Courts said schools do not have to wait for actual disruption is there is a "reasonable forecast of distrubance"
In Tinker, the Court also explained that public school officials must be able to point to evidence of disruption rather than rely on an “undifferentiated fear or apprehension of disturbance.”
The lower courts have emphasized public school officials to do not have to wait for an actual riot. The modern iteration of the test is a “reasonable forecast of substantial disruption.” For example, the 6th U.S. Circuit Court of Appeals a few years after Tinker used the substantial disruption test in Melton v. Young (1972) to rule that public school officials in Chattanooga, Tennessee, did not violate the free-speech rights of a student when they prohibited him from wearing a Confederate flag jacket to his school.
Much more recently, the 5th Circuit used the substantial disruption test in Bell v. Itawamba County School Board (2015), ruling that public school officials had a right to punish a student who posted online a rap video criticizing two teachers. The appeals court explained that the Tinker substantial disruption test still applied even though the student had created the speech entirely off-campus because his off-campus speech had a tangible impact on the school environment.
