In 2012, Chester Academy was the first school in Hudson Valley to send home 1-to-1 Google Chromebooks with its students under a plan from K-12 Director of Instruction & Technology / Data Administrator Edward A. Spence. In 2014, Chester UFSD was awards an "Innovative Schools" annual award from NYSSBA. The district has since had ten different school districts visit Chester Academy to share best practices with Mr. Spence, teachers and students regarding their award-winning 1-to-1 Chromebook Instruction Plan. Take-home 1-to-1 Chromebooks have since become the de facto standard for school districts.
The name of the school changed from Chester Jr/Sr High School to Chester Academy in May 2004 when students and faculty were moved from the original Maple Avenue school building to the new building on Hambletonian Avenue. Chester Jr/Sr High School housed students grades 7–12, and was changed to accommodate students grades 6–12 in the Chester Academy. The school building is separated into a junior high school wing and a high school wing. Chester Academy is also home to an Orange-Ulster BOCES Special Education wing.
One memorable event in the school's history was a school shooting scare in 2018. A BOCES student made a 911 call claiming that a man with a gun was in the building. What ensued was a three-hour lockdown as SWAT members swept each room of the building. Other schools in the area had a lockout, and once the truth was uncovered, no charges were pressed on the student.
