The top reported proficiency rate is 46% in English language arts. The lowest is 22% in Math.
Original Research by School Decision on 21st Century Cyber Cs
21st Century Cyber CS is a charter school serving grades six through twelve in West Chester, Pennsylvania, with an enrollment drawn predominantly from the Chester County region. The school is online and operates under the same charter authorization as the 21st Century Cyber Charter School district.
The school's state assessment results show performance well below the Chester County median. In English Language Arts, slightly less than half of tested students in grades three through eight scored at proficiency; in mathematics, proficiency fell to about one in five. Across both subjects the school ranks in the bottom quartile among the county's districts on an overall proficiency index. State testing data does not yet show multi-year trends that would reveal whether performance is improving, stable, or declining. The school does not report a graduation rate or chronic absenteeism data; data on students with individualized education plans and English learners are also missing.
The student body is predominantly white and includes a very small share of students qualifying for free or reduced-price lunch. The school draws a broad cross-section from its grade band: sixth grade enrollment is small, but the school grows substantially into middle school and then levels out in the high school grades, suggesting it functions partly as an onramp for students entering cyber education at sixth or seventh grade and partly as a stable high school pathway for those who continue. Special population counts are not reported, so the degree to which the school serves students with disabilities or language-learning needs cannot be determined from available data.
Online learning creates a very different environment from traditional school. Parents choosing 21st Century Cyber should expect asynchronous coursework, self-directed pacing, and home-based instruction. This model suits some learners—those with scheduling conflicts, documented learning differences, severe anxiety in group settings, or a need for one-to-one attention—and does not suit others, particularly younger adolescents who benefit from daily peer interaction and in-person adult oversight. The school's grade band starts at sixth grade, which is notably young for fully remote learning; a parent may want to look into further with the school how sixth and seventh graders specifically are supported, structured, and monitored.
West Chester itself is an active, walkable borough and county seat with a downtown anchored by restaurants, shops, and cultural institutions, and immediate proximity to West Chester University. Housing values in the zip code are above the Pennsylvania state median, and the market has been appreciating. The borough is in a period of substantial multifamily development, which could reshape local character and school-age population over the next several years.
The school operates under new constraints that families should be aware of. Pennsylvania's 2025 state budget imposed a requirement that cyber charter parents submit proof of residence twice yearly, a standing obligation for 21CCCS families. More significantly, the school has agreed in principle to an enrollment cap as part of its charter renewal, which means future spots may become harder to secure. Additionally, the state enacted a new cyber charter funding formula in late 2025 that reduces the per-pupil revenue districts pay to charters, potentially pressuring the school's long-term budget and program offerings. These policy shifts are recent and ongoing, and a parent considering enrollment should ask the school directly how it is managing these constraints and what they mean for curriculum depth and services in the years ahead.
