For families evaluating private school options, understanding how these institutions measure and report student achievement is a critical part of the decision-making process. Unlike public schools, which are typically mandated to participate in state-administered standardized tests, private schools operate with greater autonomy in their assessment choices. This leads many parents to ask a pivotal question: how do private schools contribute to or participate in national educational assessments? The answer is multifaceted, involving voluntary participation, the use of independent standardized tests, and a focus on sharing data that aligns with their specific educational missions.
Voluntary Participation in National and Standardized Testing
Private schools are not bound by federal or state laws to administer the same annual standardized tests as public schools, such as state-specific accountability exams. However, a significant number choose to participate in nationally norm-referenced assessments voluntarily. These tests provide a benchmark for comparing student performance against a national sample of peers. According to data from the National Association of Independent Schools (NAIS), many member schools utilize tests like the ERB's Comprehensive Testing Program (CTP), the Iowa Assessments, or the Stanford Achievement Test. This voluntary participation allows schools to gather objective academic data, inform curriculum adjustments, and provide families with a transparent look at aggregate student progress.
Independent Use of College Entrance and Readiness Exams
A primary way private schools, particularly at the high school level, engage with national assessment frameworks is through college entrance exams. The SAT and ACT are universally recognized benchmarks, and private schools often have robust programs to prepare students for these tests. Many schools administer the PSAT, which is linked to the National Merit Scholarship Program, to all students in grades 10 and 11. Performance on these exams is a key metric schools track and report, as it directly relates to college admissions outcomes-a major consideration for families. This data often forms a core part of a school's profile and is shared in admissions materials.
Contribution to Educational Research and Benchmarking
Beyond mandated tests, private schools contribute to the broader educational landscape through participation in independent studies and consortium benchmarking. Organizations like the Educational Records Bureau (ERB) and the Northwest Evaluation Association (NWEA), which administers the MAP Growth assessments, aggregate anonymized data from their member private schools. This pooled data contributes to national normative studies and helps schools compare their students' growth and achievement to those in similar independent institutions across the country. This practice allows private schools to engage in data-driven improvement while contributing to a larger body of educational research.
Accreditation and Self-Study as an Assessment Model
For many private schools, a rigorous form of "assessment" comes through the accreditation process. Regional accrediting bodies, such as the New England Association of Schools and Colleges (NEASC) or the Western Association of Schools and Colleges (WASC), require member schools to undergo periodic self-studies and external reviews. This process involves a deep, holistic evaluation of the entire school program-from academic rigor and student learning outcomes to mission fulfillment and operational health. The resulting accreditation reports are a form of qualitative and quantitative assessment that holds schools accountable to high national standards, even without state testing mandates.
What This Means for Parents Researching Schools
When touring schools or reviewing their materials, parents should proactively inquire about assessment practices. Key questions to ask include:
- Which nationally norm-referenced tests, if any, does the school administer, and in which grades?
- How does the school use the results from these tests to support individual students and improve teaching?
- What are the school's average or median SAT/ACT scores, and how does it support college test preparation?
- Is the school accredited, and by which organization? May I review the most recent accreditation report?
- How does the school measure and report on student progress beyond standardized test scores?
Understanding a school's approach to assessment will provide a clearer picture of its commitment to academic excellence, transparency, and continuous improvement. It is essential to verify all specific testing policies, reporting practices, and accreditation details directly with each school, as these can vary significantly between institutions.
