[3] Manhasset students were previously authorized to study at Flushing High School or in Great Neck per inter-district agreements.

Manhasset High School has a 98% four-year graduation rate according to 2017–2021 data, coming in significantly ahead of the New York state average of 86%.

[12] According to the American Community Survey Education Tabulation (ACS-ED) for 2015–19, the Manhasset UFSD has a population of 16,847 residents total across 5,547 households.

The sport would grow in popularity in the area over the coming decades, with Long Island overtaking Maryland as the top region for high school lacrosse in the United States by the 1960s.

Many top college lacrosse players have been recruited from Long Island high schools, including Manhasset.

[19] In the prior edition of The Tower, the school's athletic teams are only referred to as "The Orange and Blue", an appellation also used for them in 1939 alongside "Indians".

[20] At this point in time, no visual "Indians" name or related iconography appeared on team uniforms, at least as worn in contemporary yearbooks.

However, citing a desire to seek local remedies for problems before giving orders, Mills did not require any particular course of action, issuing a mere suggestion.

Montaukett activist Sadanyah FlowingWater and Shinnecock tribe member Jeremy Dennis called for the school to end its use of the "Indian" mascot.

"[26] At the October 22 board meeting, also attended by speakers from the local Montaukett, Shinnecock, Ungechauk, Setalcott and Matinecock nations, Manhasset residents, students and alumni voiced their opinions on the team name and mascot.

Some interlocutors also pointed out the awkwardness of the use of the term "Indian" to refer to not only the indigenous peoples of the Americas (and consequently the sports teams) but also members of Manhasset's Indian-American community.

By this time, in line with Butera's 2020 promise, the "Indian head" logo had been replaced by the "M with a feather" on team uniforms and in a number of locations around the school.

The proponents of the Indians mascot wrote of "Rumors of a new image" corroborated by "clear changes [which] have been made around the building" and demanded the school "immediately stop proceeding with the backdoor termination of our Indian image and rather speak with the proud Manhasset community before any changes are made."

Claiming to "represent this culture with the utmost respect", the seniors also called for an "Indian Appreciation Day" dedicated to indigenous leaders teaching about their heritage.

[30][31] Meanwhile, in upstate New York, the Cambridge Central School District in Cambridge, New York was ordered by State Education Commissioner Betty A. Rosa to cease use of a similar "Indians" name and mascot by the end of the 2021–22 school year, as she found it inhibited a "a safe and supportive environment" for students; local opponents of the change are contesting the decision.

[36] On June 11, 2024, Superintendent Guarav Passi announced that, after consultation with the community, no new mascot would be adopted, and that the teams would be identified simply as Manhasset or 'Set.

[37] Students must pass at least one class in the arts in order to receive a Regents Diploma from Manhasset High School.

[39][40][41] Manhasset music students are regularly among the selectees for NMEA All-County, NYSSMA All-State and NAfME All-Eastern and All-National honor ensembles.
