Renaissance Star Scores: Scaled Scores, Percentiles, and Growth
A Renaissance Star score report may include several measures of achievement, growth, and benchmark status.
The exact report depends on whether the student took Star Reading, Star Math, Star Early Literacy, or another Star assessment.
For parents:
Begin by confirming the exact Star assessment. A Star Reading score should not be interpreted in the same way as a Star Math or Star Early Literacy score.
Optional TestPrep-Online preparation:
When your school permits practice, families can review TestPrep-Online Star practice packs, Renaissance Star preparation overview and TestPrep-Online Family Membership. Confirm the assessment, grade or level, current pack contents, access terms, and school policy before purchasing.
Which Scores May Appear?
Depending on the assessment and report settings, you may see:
- Scaled Score;
- Percentile Rank;
- Student Growth Percentile;
- Grade Equivalent;
- benchmark category;
- domain or instructional-area information;
- Lexile measure or range;
- Quantile measure or range;
- Zone of Proximal Development;
- estimated proficiency information;
- progress toward a local goal.
Not every report includes every score.
What Is a Star Scaled Score?
The Scaled Score, often abbreviated as SS, represents performance on the relevant Star measurement scale.
Renaissance calculates it using information such as:
- the difficulty of the questions administered;
- the student’s responses;
- the assessment’s scoring model.
A Scaled Score is not:
- a percentage correct;
- a percentile;
- a classroom grade;
- a Grade Equivalent;
- an IQ score;
- a universal pass mark.
Scaled Scores can be used to compare performance over time within the appropriate Star assessment and scale.
Can Star Scores Be Compared Across Subjects?
Do not directly compare a Star Reading Scaled Score with a Star Math Scaled Score.
The assessments measure different subjects, and a higher number in one subject does not mean that the student is stronger than in another subject.
When comparing results over time, confirm:
- the same subject;
- the same or compatible scale;
- valid test administrations;
- reasonably comparable testing conditions;
- an appropriate interval between tests.
What Is Percentile Rank?
Percentile Rank, or PR, compares the student’s achievement with an appropriate national norm group.
Percentile Ranks generally range from 1 to 99.
For example, a Percentile Rank of 70 means the student scored as well as or better than approximately 70% of students in the comparison group.
It does not mean that the student answered 70% of the questions correctly.
Percentile interpretation depends on:
- the Star assessment;
- grade;
- testing period;
- applicable norms;
- report settings.
What Is Student Growth Percentile?
Student Growth Percentile, or SGP, describes a student’s growth relative to academic peers with a similar score history.
SGP values range from 1 to 99.
For example, an SGP of 65 indicates that the student showed more growth than approximately 65% of comparable academic peers.
SGP does not show current achievement.
| Measure | Main question |
|---|---|
| Percentile Rank | How does current achievement compare with the norm group? |
| Student Growth Percentile | How does recent growth compare with academic peers who had a similar score history? |
A student can have high achievement and lower growth, or lower achievement and strong growth.
What Is a Grade Equivalent?
A Grade Equivalent compares the student’s test performance with typical performance associated with a grade and month.
It does not mean that the student:
- has mastered the complete curriculum at that grade;
- should automatically move to that grade;
- can complete every task at that level;
- should skip a grade;
- has identical skills across all domains.
Grade Equivalent scores are frequently misunderstood because they resemble school-grade labels.
Do not use Grade Equivalent alone:
It should not be the sole basis for curriculum selection, placement, acceleration, or intervention.
What Are Benchmark Categories?
A Star report may classify performance into benchmark categories.
Labels can include:
- At or Above Benchmark;
- On Watch;
- Intervention;
- Urgent Intervention;
- Meets Benchmark;
- Below Benchmark;
- locally configured levels.
The labels and cut scores can depend on:
- the assessment;
- grade;
- testing period;
- state standards;
- district settings;
- benchmarks selected by the school.
A benchmark category is a decision-support label, not a diagnosis or permanent description of the child.
Can Schools Change the Benchmark?
Schools and districts may use default benchmarks, state benchmarks, or locally configured cut scores.
This means that two schools can display different benchmark labels for similar scores.
Ask which benchmark system appears on the report and how it will be used.
What Are Domain or Instructional-Area Results?
Some Star reports provide information about performance across broad areas.
Reading examples
- foundational skills;
- vocabulary;
- literature;
- informational text;
- comprehension.
Mathematics examples
- numbers and operations;
- algebra;
- geometry and measurement;
- data analysis;
- statistics and probability.
Early literacy examples
- phonological awareness;
- phonics;
- word recognition;
- vocabulary;
- comprehension;
- early numeracy.
Domain estimates can help identify possible instructional priorities, but they are often based on fewer questions than the overall result and should be interpreted cautiously.
What Is a Lexile Measure?
A Star Reading report may include a Lexile measure or range.
It can help match reading ability with text complexity.
Lexile information does not fully account for:
- interest;
- background knowledge;
- emotional maturity;
- literary quality;
- subject matter;
- illustrations;
- teacher or adult support.
It should guide reading selection rather than restrict it.
What Is a Quantile Measure?
A Star Math report may include a Quantile measure or range.
It can help educators understand which mathematical skills and concepts may be appropriately challenging and how skills relate across a learning progression.
It should not be treated as a complete curriculum or a simple grade-level label.
What Is a Good Star Score?
There is no single Star score that is good for every student.
Interpretation depends on:
- the exact Star assessment;
- grade;
- testing period;
- applicable norms;
- previous scores;
- growth;
- benchmark settings;
- classroom performance;
- the purpose of the assessment.
A result above the national median does not guarantee gifted placement, admission, promotion, or future academic success.
A result below the median does not independently diagnose a learning disability.
Is There a Star Passing Score?
There is no universal Star pass mark.
A school or district may apply local criteria for:
- intervention;
- instructional grouping;
- enrichment;
- course placement;
- programme eligibility;
- progress monitoring.
Those local criteria should not be presented as universal Renaissance thresholds.
What Does a Lower Score Mean?
A lower result may indicate difficulty with some of the measured skills, but the school should also consider:
- whether the correct assessment was assigned;
- testing conditions;
- illness, fatigue, or anxiety;
- rushing or disengagement;
- language background;
- consistency with classroom evidence;
- previous results;
- measurement uncertainty;
- the domain pattern.
One lower score should not automatically be treated as proof of lost learning or a particular diagnosis.
Can Star Identify a Learning Disability?
No Star score can independently diagnose dyslexia, dyscalculia, ADHD, a language disorder, or another learning or developmental condition.
A pattern may indicate that further investigation is appropriate, but formal evaluation requires additional evidence and professional interpretation.
Can Star Identify Gifted Students?
Some schools may use Star results as one source of evidence during gifted or advanced-programme screening.
They may also consider:
- repeated achievement results;
- classroom work;
- teacher recommendations;
- cognitive assessments;
- portfolios;
- local screening criteria.
There is no universal Star score that automatically qualifies a student for a gifted programme.
How to Read a Star Report
A useful order is:
- Confirm the assessment and subject.
- Check the testing date and grade.
- Find the Scaled Score.
- Review the Percentile Rank.
- Review Student Growth Percentile separately.
- Identify the benchmark category and benchmark type.
- Examine domain or instructional-area results.
- Review Lexile, Quantile, or reading-range information where provided.
- Compare the report with classroom evidence and previous results.
- Ask what instructional action will follow.
