For decades, Prosper ISD only operated one high school. However, the Town of Prosper and surrounding areas in Collin County experienced substantial population growth throughout the late 2010s, and Prosper High School began to face concerns of overcrowding. In response, the district began construction of a second high school in 2018. The project was budgeted at over $200 million, which made it the most expensive public high school in Texas at the time.
The new campus, or “High School #2” as it was referred to, was named Rock Hill High School and opened its doors for the 2020-2021 school year. The school was named after Rockhill Parkway, the former name of PGA Parkway, a major arterial road that intersects with Coit Road, where the school is located. It is unclear why the school’s name includes a space between Rock and Hill when both the former roadway and the census tract do not. The school is still occasionally referred to informally as “Rockhill High School.”
As the 2020–2021 academic year was amidst the COVID-19 pandemic, Rock Hill’s inaugural year saw many students attending virtual classes or alternating between online and in-person instruction. This option was discontinued after the first year.
The school’s initial attendance zone encompassed the southern and eastern portions of the district. Students residing within this area who found themselves zoned to the new school but were already upperclassmen at Prosper High School were allowed to pick between remaining at their current campus or transferring to Rock Hill. Underclassmen, however, were required to transfer to Rock Hill.
Rock Hill opened as a UIL Class 5A school but was reclassified as a 6A school starting from the 2022–23 school year. It was one of the smallest 6A schools in the state in terms of enrollment.[2]
In 2023, the district opened its third high school, Walnut Grove High School, and a many Rock Hill students were reassigned to the new campus. This caused a significant decrease in enrollment, pushing Rock Hill further down the 6A threshold. Nonetheless, Rock Hill remains a 6A school, as the UIL only reclassifies schools in non-leap, even-numbered years.
With Walnut Grove opening, Rock Hill’s first principal, Dr. Dustin Toth, was appointed as the inaugural principal of Walnut Grove High School. One of the five assistant principals, Terry Mouton was subsequently promoted to principal of Rock Hill and continues to serve in that role. [3]
Controversy
In February 2021, J. P. Wilson, the head band director of Rock Hill High School, resigned after allegations of sexual misconduct from previous workplaces had surfaced. The district did not publicly disclose a reason for the resignation.
In January 2023, Drew Wilborn, then-president of the Prosper ISD Board of Trustees, resigned following his arrest on a charge of indecency with a child by sexual contact. The incident involved allegations of inappropriate relations with a 16-year-old girl in April 2022, while Wilborn was serving as an executive pastor at Antioch Fellowship Missionary Baptist Church.
Later that year, the family of a Rock Hill alumna filed a federal civil rights lawsuit against the school, alleging that their daughter was subjected to disability-based discrimination and retaliation. The complaint claimed the district failed to provide proper accommodations for her diagnosed ADHD and learning differences, and that school staff retaliated after her parents raised concerns.
In August 2023, head softball coach Renna Bersosa and assistant coach Kasie Ostrom were arrested for failing to report a sexual assault. A student informed the coaches of sexual misconduct by other students on the team. Despite probable evidence, the coaches dismissed the issue, failing to report within the 48-hour window required under Texas law. Both were charged with failure to report child abuse.
In May 2025, Staff Sergeant Michael Songy, the assistant JROTC instructor at Rock Hill High School, was arrested on a charge of indecent assault with a student. Songy had been previously reported to the Texas Education Agency in July 2024 for sexual misconduct in school, but was granted an emergency recertification in August 2024 to teach in the district’s new JROTC program.
Later that month, a senior celebration event attended by students from Rock Hill and Walnut Grove, resulted in several hospitalizations after students consumed THC-laced edibles. At least one Rock Hill student was among those affected. Two students were later arrested and charged with felony drug distribution. The event had been a prepaid celebration, and despite a community petition requesting refunds, Prosper ISD declined to issue reimbursements.
