The Mastery Charter High School Data Breach: Incident Facts and Free Case Review

Mastery Charter High School is an educational institution responsible for the academic and administrative management of its student body. Schools of this nature typically collect and maintain sensitive personal information, including student academic records, government-issued identification numbers, and family contact details required for enrollment and financial aid processing. In 2025, the school officially reported a data security incident to the New Hampshire Attorney General, confirming that unauthorized access to its digital systems occurred. If you received a formal data breach notification letter, it indicates that your personal information or that of your dependent may have been compromised during this event. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered by the school.
