Race‑norming, more formally called within‑group score conversion and score adjustment strategy, is the practice of adjusting test scores to account for the race or ethnicity of the test‑taker. In the United States, it was first implemented by the Federal Government in 1981 with little publicity, and was subsequently outlawed by the Civil Rights Act of 1991. Prior to being banned by the federal government, race‑norming was practiced by 38 U.S. states’ employment services. The aim of this practice is to counteract alleged racial bias in aptitude tests administered to job applicants, as well as in neuropsychological tests. The argument was that it guarantees racial balance. The practice converted and compared the raw score of the test according to racial groups. The score of a black candidate is only compared to the scores of those who had the same ethnicity. If the candidate’s score, which is reported within a percentile range, fell within a certain percentile when compared to white or all candidates, it would be much higher among other black candidates.
1. Introduction
The measurement of human ability and performance has long been a cornerstone of modern society, from educational placement to hiring decisions and clinical assessment. Over the decades, the fairness of these measurements has been a subject of intense scrutiny. One of the most controversial responses to concerns about racial bias in testing was race‑norming—a method that sought to level the playing field by adjusting scores based on the test‑taker’s racial or ethnic group. While its proponents argued that the method addressed inherent biases in test construction, critics saw it as a form of reverse discrimination. The practice ultimately faced legal challenges and was banned under the Civil Rights Act of 1991.
This article delves into the origins, mechanisms, rationale, legal status, and legacy of race‑norming. By unpacking the factual history and the logic behind the practice, we aim to provide a clear understanding of why it mattered and how it shaped contemporary discussions about test fairness and equal opportunity.
2. Definition of Race‑norming
Race‑norming is a statistical adjustment technique that converts raw test scores into percentile ranks that are specific to a test‑taker’s racial or ethnic group. Rather than comparing a candidate’s raw score directly to a national or overall distribution, the method compares it to the distribution of scores produced by individuals of the same racial group. The resulting percentile is then used to interpret the candidate’s performance.
Key points:
- Within‑group conversion: The raw score is first converted to a percentile rank within the candidate’s racial group.
- Comparison across groups: The percentile rank is then interpreted relative to the overall distribution of percentiles across all racial groups.
- Purpose: The intended outcome is to reduce the impact of any systemic bias that may favor one group over another in raw scores.
Race‑norming is also referred to as score adjustment strategy because it adjusts the interpretation of scores rather than the scores themselves.
3. Historical Background
3.1 Federal Implementation (1981)
The first federal implementation of race‑norming occurred in 1981. The Federal Government introduced the practice with minimal public announcement. While the exact agencies involved are not specified in the source, the federal adoption signaled the recognition of perceived racial disparities in standardized testing.
3.2 State Adoption (38 States)
Before the federal ban, 38 U.S. states adopted race‑norming in their employment services. These states applied the practice in the evaluation of job applicants, aiming to mitigate alleged racial bias in aptitude tests. The widespread state-level adoption underscored the prevalence of the method across the country.
3.3 Legal Challenge and Ban (1991)
The Civil Rights Act of 1991 outlawed the practice of race‑norming. The Act, a federal civil rights statute, prohibited the use of racial or ethnic group comparisons in employment testing. The ban effectively ended the formal use of race‑norming in federal and state employment services.
4. Mechanism of the Practice
4.1 Raw Score Conversion
When a candidate takes an aptitude or neuropsychological test, they receive a raw score—the sum of points earned from correct responses. Race‑norming first transforms this raw score into a percentile rank relative to a reference group of the same race or ethnicity.
4.2 Within‑Group Comparison
The percentile rank reflects how the candidate’s raw score compares to other test‑takers of the same racial group. For example, a black candidate who scores in the 70th percentile within the black population is considered better than 70 % of black test‑takers.
4.3 Percentile Reporting
The resulting percentile is then reported as part of the candidate’s test profile. Importantly, the percentile is used to interpret the candidate’s performance in the context of the overall distribution of percentiles. The source notes that if the candidate’s percentile falls within a certain range when compared to white or all candidates, it would be much higher among other black candidates. In other words, a black candidate who is in the 70th percentile relative to the black population may be in the 90th percentile when compared to the overall population, reflecting the adjustment.
5. Rationale and Intended Goals
Proponents of race‑norming argued that the method:
- Counteracts alleged racial bias in test construction or administration, which may favor one group over another.
- Guarantees racial balance in hiring or placement decisions by ensuring that each racial group is evaluated on its own distribution of scores.
- Provides a more equitable comparison for neuropsychological tests, which assess cognitive functioning across diverse populations.
The central claim is that raw scores may be influenced by cultural, educational, or socioeconomic factors that differ systematically across racial groups. By adjusting scores within each group, the practice aims to neutralize those influences.
6. Legal Status and Banning
6.1 Civil Rights Act of 1991
The Civil Rights Act of 1991 explicitly prohibited the use of race‑norming in employment testing. The ban was grounded in the principle that equal treatment in hiring should not involve comparing test results across racial lines. The Act’s enforcement rendered the practice illegal at both the federal and state levels.
6.2 Aftermath
Following the ban, employers and testing agencies had to abandon race‑norming. They shifted to other methods for addressing test fairness, such as developing tests with minimal cultural bias or employing alternative assessment strategies.
7. Impact and Legacy
Although race‑norming is no longer legally permitted, its legacy remains in several ways:
- Awareness of Racial Bias: The practice highlighted the perception that standardized tests could disadvantage certain racial groups, prompting further research into test fairness.
- Legal Precedents: The ban under the Civil Rights Act set a legal precedent against practices that differentiate based on race in employment contexts.
- Ongoing Debates: The conversation around race‑norming continues to influence modern discussions about affirmative action, group‑based assessment, and the ethics of statistical adjustments.
The method’s removal from practice has led to increased scrutiny of how test scores are interpreted and how employers can ensure equitable hiring without violating anti‑discrimination laws.
8. Current Status
Today, race‑norming is prohibited in the United States. Employers and testing organizations must rely on other methods to address potential biases. These include:
- Culturally responsive test design: Creating tests that minimize cultural or linguistic bias.
- Statistical fairness analyses: Using modern psychometric techniques to evaluate test bias.
- Holistic hiring practices: Combining test scores with interviews, work samples, and other assessment tools.
Because the practice is illegal, it is not employed in any state or federal employment service. The historical record of race‑norming serves as a cautionary example of how well‑intentioned statistical adjustments can conflict with civil rights law.
9. Conclusion
Race‑norming emerged as an attempt to level the playing field for test‑takers from different racial or ethnic groups. By converting raw scores into within‑group percentiles, the practice sought to counteract alleged biases in aptitude and neuropsychological tests. However, the method was ultimately deemed illegal under the Civil Rights Act of 1991, and its use was banned across the United States.
While the practice itself is no longer in use, its history underscores the complexities of ensuring fairness in testing. It reminds us that statistical adjustments can have profound legal and ethical implications. Contemporary approaches to test fairness must balance the need to mitigate bias with adherence to anti‑discrimination laws, often relying on improved test design, rigorous psychometric analysis, and holistic assessment strategies.
