7.5 Interpreting Achievement Tests: Fairness, Culture, and Accommodations
Key Takeaways
ESSA requires annual state reading and math tests in grades 3–8 and once in high school, plus science once in each grade span.
A grade equivalent compares a score with typical students at other grades; it does not show mastery of higher-grade content.
Language demands, opportunity to learn, poverty, test anxiety, stereotype threat, and norm-group mismatch can make a score less valid for a student.
Accommodations change presentation, response, setting, or timing without changing what a test measures.
ASCA A.14 requires valid, reliable, culturally sensitive tests, multiple data points, and interpretation in terms students and families understand.
7.5 Interpreting Achievement Tests: Fairness, Culture, and Accommodations
Quick Summary: ETS expects counselors to interpret achievement tests and other measures of learning and to know how cultural, social, and environmental influences affect test performance, test accommodations, and test interpretation. ASCA Standard A.14 requires valid, reliable, culturally sensitive assessments, multiple data points, and interpretation in terms students and families understand.
Types of Achievement Measures
| Measure | What It Tells You | Interpretation Caution |
|---|---|---|
| State accountability tests (ESSA requires annual reading and math tests in grades 3–8 and once in high school, plus science once in each grade span) | Performance levels against state standards (criterion-referenced) | Cut scores differ across states; each result is one snapshot |
| Interim or benchmark assessments given in fall, winter, and spring | Growth during the year, national percentiles, scale scores | Look at growth and trends, not one score |
| Classroom grades and GPA | Mastery mixed with effort, behavior, and grading practices | Grading policies vary by teacher |
| College entrance and placement exams (PSAT/SAT, ACT, AP scored 1–5) | Readiness benchmarks and college credit potential | Access to preparation differs by income |
| Norm-referenced achievement batteries | Standing compared with a national norm group | The norm group must represent the student |
Reading a Score Report
- Scale scores allow comparison across test forms; performance levels (for example, basic or proficient) translate scale scores into categories.
- Percentile rank compares a student with the norm group; it is not the percentage of items correct (see 7.1).
- Grade equivalents are easy to misread. A fourth grader with a grade equivalent of 7.2 on a fourth-grade reading test scored the way a typical seventh grader might score on that fourth-grade test; it does not mean the student has mastered seventh-grade content or should skip grades.
- Growth measures (such as student growth percentiles) compare a student's progress with that of academically similar peers.
- Standard error of measurement (SEM): interpret a band, not a point. ETS reports an SEM of 5.1 points for the Praxis 5422, so a score of 157 suggests a true score of roughly 152–162 about 68% of the time.
Cultural, Social, and Environmental Influences on Test Performance
- Language proficiency: a math test written at a high reading level partly measures English rather than math—construct-irrelevant variance that lowers validity for English learners.
- Opportunity to learn: students cannot show what they were never taught; course access and school resources differ.
- Socioeconomic factors: hunger, sleep, stress, and access to test preparation.
- Stereotype threat (Claude Steele and Joshua Aronson, 1995): when a negative stereotype about a student's group is made salient, performance can drop; framing tests as learning tools and affirming students' values reduces the effect.
- Test anxiety and testwiseness: familiarity with formats and calm under time pressure affect scores.
- Item bias: content that assumes experiences some students lack. Publishers review items for bias and study differential item functioning, but local interpretation still matters.
- Norm-group mismatch: ASCA A.14 cautions against relying on instruments normed on populations that do not include the student's group.
Test Accommodations
Accommodations change how a test is given without changing what it measures.
| Category | Examples |
|---|---|
| Presentation | Large print, braille, translated directions, read-aloud where reading is not the skill measured |
| Response | Scribe, speech-to-text, marking answers in the test booklet |
| Setting | Separate room, small group, reduced distractions |
| Timing and scheduling | Extended time, breaks, a different time of day |
- Students with IEPs or 504 plans receive the accommodations their plans specify, following the state's accommodations manual.
- English learners may receive state-approved supports, such as word-to-word bilingual glossaries or directions in the home language.
- College Board and ACT accommodations require separate approval; counselors help families apply, often with the school's coordinator for those requests.
- Coordinating the schoolwide testing program is an inappropriate counselor duty under ASCA, but interpreting results and advocating for appropriate accommodations are appropriate.
Ethical Interpretation (ASCA A.14)
School counselors:
- Use valid, reliable, research-based tests that are culturally sensitive, in the student's preferred language, and free of bias.
- Consider the student's developmental age, language skills, home language, and competence when judging whether an assessment is appropriate.
- Use multiple data points, quantitative and qualitative.
- Explain the nature, purpose, results, and impact of assessments in the student's preferred language and in terms students and parents understand.
- Take reasonable steps to prevent others from misusing results.
The Standards for Educational and Psychological Testing (AERA, APA, and NCME, 2014) likewise call for multiple measures before high-stakes decisions.
Using Results in Planning
Combine test data with grades, attendance, and student voice to place students fairly (for example, open access to advanced courses with support), identify students for intervention, and communicate strengths as well as needs.
Praxis Application
Scenario: A newcomer English learner earns a low score on an English-language math test full of long word problems, and a teacher recommends placing him in remedial math.
Analysis: The score likely reflects language demands as much as math skill. The counselor gathers other evidence—classroom work, native-language or low-language-load math tasks, prior records—and advocates for placement based on multiple measures, with language supports.
A fourth grader earns a grade equivalent of 7.2 on a fourth-grade reading achievement test. How should the counselor explain this result to the parents?
The student has mastered seventh-grade reading content and should move to seventh grade
The student answered 72% of the items correctly
The student performed on fourth-grade material the way a typical seventh grader might, which signals strong reading skills but not mastery of seventh-grade content
The student is 7.2 years behind grade level
A newcomer English learner scores poorly on a math test made up of long English word problems. Which concept best explains why the score may underestimate the student's math skill?
Construct-irrelevant variance from language demands
High test-retest reliability
Regression to the mean
Content validity for the student's previous curriculum
A student with a 504 plan for a visual impairment is taking the state reading test. Which change is an appropriate testing accommodation?
Reading the comprehension passages aloud to the student
Allowing the student to skip half of the items
Letting the counselor give hints on difficult items
Providing large-print or braille materials and extended time as specified in the plan
