Moving Up to JHS


Memories and success stories flooded the minds of parents, students and educators in the Three Village Central School District as the elementary schools marked a milestone in the lives of this year’s sixth-grade class.

During the moving-up ceremonies, students reflected upon their years in each building, while faculty and staff members presented awards honoring individual scholars’ academic, athletic and community-minded achievements.

Melodic interludes at each ceremony showcased the students’ myriad of musical talents and left audiences with fond memories.

Just before the conclusion of each ceremony, the schools’ graduating classes were announced. As the students left their schools on this special day filled with an array of emotions, they were well prepared for life’s adventures ahead.

Commending Achievements

The Board of Education honored and celebrated a myriad of accomplishments of both the district’s students and staff members at its June meeting.

W.S. Mount Elementary School second-grader Ryan Scriven was honored for his award-winning piece in this year’s New York State Association for Pupil Transportation School Bus Safety Poster Contest. Ryan received third place in Suffolk County for the K-2 division. His poster followed the contest’s theme of making the school bus a bully free zone.

Secondary student-scientists from R.C. Murphy and P.J. Gelinas junior high schools were honored for their successful competition seasons.

Murphy’s Science Bowl team was commended for their win at the Brookhaven National Laboratory/Long Island Regional Middle School Science Bowl contest. The team competed in the National Science Bowl Contest this spring.

Gelinas’ Science Olympiad team was also recognized for their 10th place finish at the National Science Olympiad Competition and for earning eight medals in the contest, including three first-place awards.

Gelinas eighth-grader Sahil Sangwan represented his school and district during this year’s National Spelling Bee in late May, making it to the third round.

The Board also thanked student representative George Zenzerovich for his year of service and presented the soon-to-be graduate with a scholarship for his continued education.

Mount Math Masters

W.S. Mount Elementary School’s Mount Math Masters teams captured first and second place at the Suffolk County Math Tournament at Stony Brook University. Additionally, the students received 10 individual trophies for earning top 10 honors at the contest.

The school was represented at the contest by two sixth-grade teams, which were comprised of a mix of sixth and fifth-grade students. They competed against 52 teams made up of more than 250 contestants at the event.

They prepared for the event under the direction of Linda Earls by participating in the Math Olympiads, monthly challenges given around the country. For the first time this year, a Mount student – Alex Lin – received a perfect score in the Math Olympiad.

Congratulations to the following individual trophy winners:

Claire Yang (fifth-grader) – First place
Alice Liu (sixth-grader) – Second place
Carolyn Liu (fifth-grader) – Third place
Jedidiah Tan (sixth-grader) – Fifth place
Julia Zhu (sixth-grader) – Sixth place
Alex Lin (fifth-grader) – Seventh place

A Golden Ticket

W.S. Mount Elementary School’s Drama Club performed their first musical – “Willy Wonka” – before packed audiences this May.

The 45-member cast dedicated countless hours toward making the production a success, rehearsing from December through May under the direction of teachers Dan Hayes and Gretchen Tranchino and choreographer Lauren Horn. The lighting design for the show was provided with the help of several Ward Melville High School students.
