Private School Enrollment Trends (2011–2021): What the Data Suggests for Student Support and Service Planning

Why private school enrollment data matters for school service planning

For school leaders, enrollment is more than a headcount—it is a planning variable that shapes staffing, budgets, space utilization, and the design of student support services. Private schools face many of the same pressures as public systems (student needs, staffing constraints, and service continuity), but they often operate with different funding structures and governance models. As a result, understanding private school enrollment patterns can help administrators anticipate demand for specialized supports such as speech-language therapy, occupational therapy, and mental health services.

Using findings summarized in the National Center for Education Statistics (NCES) Condition of Education 2024, this post highlights key private school enrollment trends through fall 2021 and translates them into practical considerations for service delivery models—including online therapy services for schools.

Private school enrollment in 2021: a stable share of the K–12 landscape

In fall 2021, approximately 4.7 million kindergarten through grade 12 students were enrolled in private schools. This represented 9 percent of combined public and private K–12 enrollment. Notably, private school enrollment was 4.5 million in fall 2011, meaning 2021 enrollment was about 5 percent higher than a decade earlier—yet NCES reports no measurable trend across the period.

Two points stand out for planning purposes:

• Private enrollment share remained consistent. Private school students accounted for 9 percent of combined enrollment in both fall 2019 and fall 2021, continuing a pattern seen throughout the preceding decade.
• Public enrollment declined during the pandemic period. Public school enrollment was 2 percent lower in fall 2021 than in fall 2019 (48.0 vs. 49.2 million). Private enrollment, in contrast, was 4.7 million in both 2019 and 2021.

For private schools, this stability can be interpreted as both an opportunity and a responsibility: consistent enrollment does not necessarily mean consistent student needs. If anything, stable enrollment can mask shifting demand for specialized services, especially when staffing markets tighten.

What “private school” includes: three orientations with different patterns

NCES defines private schools as educational institutions not primarily supported by public funds (excluding organizations that support homeschooling). In this indicator, private schools are grouped by orientation:

• Catholic (including parochial, diocesan, and private-governance Catholic schools)
• Other religious (including conservative Christian schools, schools affiliated with other denominations, and religious schools not affiliated with a specific denomination)
• Nonsectarian (not religiously affiliated)

Enrollment by orientation: shifts within a stable overall total

Even when total private enrollment appears stable, the mix of school types can change. Between fall 2011 and fall 2021, NCES reports the following differences by orientation:

• Catholic schools: 1.7 million students in 2021 vs. 1.9 million in 2011 (lower in 2021, though no measurable trend for the period).
• Other religious schools: 2.0 million in 2021 vs. 1.7 million in 2011 (higher in 2021, though no measurable trend for the period).
• Nonsectarian schools: increased from 0.9 million in 2011 to 1.1 million in 2021.

Operationally, these differences matter because service models and staffing structures can vary by orientation. For example, a growing nonsectarian segment may include schools with different expectations around contracted services, scheduling flexibility, and multi-tiered systems of support.

State-by-state variation: private enrollment is highly local

National averages can obscure the reality that private school market share varies widely by geography. In fall 2021, the percentage of K–12 students enrolled in private schools ranged from 2 percent in Wyoming and Utah to 20 percent in the District of Columbia.

Several states reported private enrollment above the U.S. average of 9 percent, including:

• Wisconsin: 15 percent
• Hawaii: 18 percent
• New York: 13 percent
• Florida: 13 percent
• Louisiana: 13 percent
• New Jersey: 12 percent
• Pennsylvania: 12 percent

This dispersion has direct implications for providers and school networks. In higher-share states, private schools may face more competition for specialized staff, and families may have more school choice options—both of which can increase expectations for timely access to therapy services. In lower-share states, private schools may be more geographically dispersed, which can make in-person staffing and travel-based service delivery less efficient.

Enrollment by race/ethnicity: participation differs from the national average

NCES reports that private school enrollment rates vary by race/ethnicity. In fall 2021, the percentages enrolled in private schools were:

• Pacific Islander: 13 percent
• White: 12 percent
• Two or more races: 11 percent
• Asian: 10 percent
• Total (national average): 9 percent
• American Indian/Alaska Native: 6 percent
• Black: 6 percent
• Hispanic: 4 percent

These differences are important for equity-focused planning. Schools that aim to broaden access or serve changing communities may see shifts in the linguistic, cultural, and learning profiles of their student body—often with implications for speech-language services, bilingual assessment considerations, and family engagement practices.

Who is enrolled in private schools? The 2021 demographic composition

Among the 4.7 million K–12 students enrolled in private schools in fall 2021, the racial/ethnic distribution was:

• 65 percent White
• 12 percent Hispanic
• 9 percent Black
• 6 percent Asian
• 6 percent Two or more races
• 1 percent American Indian/Alaska Native
• 1 percent Pacific Islander

NCES also notes that the composition differs by orientation. For example:

• Other religious schools had the highest percentage of White students (72 percent).
• Catholic schools had the highest percentage of Hispanic students (18 percent).
• Nonsectarian schools had the highest percentages of Asian (11 percent), Black (10 percent), and Two or more races (9 percent) students.

Compared with public schools, private schools overall enrolled higher percentages of White students (65 vs. 45 percent) and lower percentages of Hispanic (12 vs. 28 percent) and Black students (9 vs. 15 percent). These comparisons are descriptive, but they can help school leaders benchmark their own demographics and consider how student support programming aligns with community needs.

Additional characteristics: poverty and locale differences

Private and public school students also differed in other demographic characteristics in 2021:

• Poverty: the poverty rate for private school students was 11 percent, compared with 17 percent for public school students.
• Locale: higher percentages of private school students were in cities (43 vs. 30 percent) and suburban areas (40 vs. 39 percent).
• Locale: lower percentages of private school students were in rural areas (11 vs. 20 percent) and towns (6 vs. 11 percent).

These patterns can influence how services are delivered. Urban and suburban schools may have larger student populations and more scheduling complexity, while rural schools may face a smaller local workforce and longer travel times for specialists—conditions that often make remote service delivery more attractive.

Implications for student support services: what enrollment stability really means

Private school enrollment held steady through fall 2021, but stability in enrollment does not automatically translate to stability in capacity. Many schools—public and private—continue to navigate clinician shortages, increased documentation demands, and heightened expectations for timely intervention.

From a service planning perspective, the NCES data suggests several practical takeaways:

• Plan locally, not just nationally. With private enrollment ranging from 2 percent to 20 percent by state, staffing and vendor strategies should reflect local market conditions.
• Expect variation by school type. Orientation-level differences (Catholic vs. other religious vs. nonsectarian) can correlate with different student mixes and operational models, which can affect referral patterns and therapy scheduling.
• Design services for demographic reality. Differences in race/ethnicity composition and poverty rates may shape needs related to language development, access to outside evaluations, and family support.
• Consider delivery models that protect continuity. When hiring pipelines are uncertain, online therapy can help schools maintain consistent access to qualified clinicians and reduce disruptions caused by vacancies or travel constraints.

At TinyEYE, we work with schools to operationalize these realities through secure, school-friendly online therapy services—supporting continuity of care, flexible scheduling, and access to specialized expertise when local staffing is limited.
