Star Reading Scores by Grade Level: What Is a Good Scaled Score?

A good Star Reading score is one at or above the 40th percentile for the child's grade and the month of the test. That is Renaissance's default benchmark, and in its own table it means a scaled score of 921 in the fall of grade 3, 940 in the winter and 958 in the spring. Scaled scores run from 600 to 1400, the test has 34 adaptive questions and takes about 20 minutes, and Renaissance calls it a measure of reading achievement. It is not an IQ test. This guide sets out what each number on a Star Reading report means, gives Renaissance's cut scores by grade, explains why the same score can fall in different percentiles in fall and spring, and says what the 2024 norms changed.

What do the scores on a Star Reading report mean?

Every norm-referenced Star score is derived from the scaled score, Renaissance says in its score definitions, and the scaled score itself is calculated from the difficulty of the questions and the number answered correctly. For Star Reading the scaled score runs from 600 to 1400. You will often see 0 to 1400 on copied score charts; that range belongs to the Unified scale, which Renaissance shares with Star Early Literacy (200 to 1100) and which covers 200 to 1400 in total. The scaled score is the number to follow over time, because it can be compared across grades and test dates.

• Scaled score (SS): 600 to 1400; the base for every other number on the report
• Percentile rank (PR): 1 to 99; the share of students in the same grade at the same point in the year who scored lower, so it depends on the child's grade and the month
• Grade equivalent (GE): 0.0 to 12.9+; the grade placement for which a score is typical, not a statement of what the child can read independently
• Normal curve equivalent (NCE): 1 to 99; an equal-interval version of the percentile used mostly for research
• Student growth percentile (SGP): 1 to 99; compares growth between two test windows with students of a similar starting score
• Instructional reading level (IRL): the highest level at which the child is 80% proficient with assistance; criterion-referenced, reported from Pre-Primer to grade 12.9 and Post-High School
• Estimated oral reading fluency (Est. ORF): words correct per minute, reported only for grades 1 to 4; an estimate from the test, since the child does not read aloud
• Lexile and ZPD: a book-level range, from 100L below to 50L above the Lexile measure

Renaissance also shows a percentile rank range, so one score is not read as a point. Its example is a child with a range of 32 to 59, who is likely to score inside that range if the test is repeated within four to six weeks. That is the same idea as the margin of error on an IQ score: a single result is a band.

What is a good Star Reading score by grade level?

Renaissance's Unified Benchmarks and Cut Scores sheet, based on the 2024 norms, lists the lowest scaled score at each percentile for the first, fifth and ninth month of the school year. The 40th percentile is the line between On Watch and At/Above Benchmark, so it is the closest thing to a pass mark, and Renaissance notes that the 40th percentile is widely used as a point of proficiency. The table below gives three lines for each grade, each as fall, winter and spring scaled scores.

• Grade K: 25th 633/683/733, 40th 665/716/766, 50th 686/735/784
• Grade 1: 25th 714/750/785, 40th 740/784/827, 50th 755/803/851
• Grade 2: 25th 802/836/870, 40th 845/878/911, 50th 871/902/932
• Grade 3: 25th 882/902/921, 40th 921/940/958, 50th 940/959/978
• Grade 4: 25th 934/948/962, 40th 970/984/998, 50th 989/1002/1015
• Grade 5: 25th 971/981/991, 40th 1002/1012/1022, 50th 1019/1029/1039
• Grade 6: 25th 999/1006/1012, 40th 1029/1037/1044, 50th 1046/1054/1062
• Grade 7: 25th 1017/1022/1028, 40th 1047/1054/1060, 50th 1065/1071/1077
• Grade 8: 25th 1034/1039/1044, 40th 1066/1071/1076, 50th 1082/1087/1093
• Grades 9 to 12: 40th percentile from 1073/1076/1079 in grade 9 to a flat 1094 in grade 12

The sheet also gives estimated oral reading fluency at each cut. At the 40th percentile it is 12, 21 and 30 words correct per minute in grade 1 (fall, winter, spring), 37, 52 and 69 in grade 2, 68, 76 and 86 in grade 3, and 92, 100 and 107 in grade 4. Because these are estimates from a silent computer test, they are not the same as a teacher timing a child reading a passage aloud. For the score systems of other school tests see our guides to i-Ready scores by grade level and MAP Growth scores.

Why does the same score mean different things in fall and spring?

A percentile compares a child with others of the same grade at the same point in the year, and scores rise as the year goes on, so a fixed score slides down the percentile scale over the months. In grade 3 the fall 40th percentile is 921 and so is the spring 25th percentile. A child who scores 921 in September is at the benchmark line; a child who scores 921 in May is at the Intervention line. Nothing about the child changed between the two readings except the calendar. The scaled score is the same, the percentile is not, and Renaissance says the percentile is based on the grade placement at the time of the test. This is also why no single list converts a scaled score to a percentile: you need the grade and the month too.

The same table shows how much of the year's growth to expect. The median (50th percentile) scaled score rises from fall to spring by 96 points in grade 1, 61 in grade 2, 38 in grade 3, 26 in grade 4, 20 in grade 5 and 11 in grade 8, then by only 4 in grade 11 and not at all in grade 12. Between one fall and the next, the median rises by 116 points from grade 1 to grade 2, 69 from 2 to 3, 49 from 3 to 4, 30 from 4 to 5 and 27 from 5 to 6, and by 8 or fewer after grade 8. These are our calculations from Renaissance's published cut scores. They show why a gain of 30 points means something different in grade 2 than in grade 7.

What does a grade equivalent mean, and can it be below grade level on benchmark?

A grade equivalent is a percentile in another form. Renaissance defines it as the grade placement of students for whom a score is typical, and warns that a GE of 3.4 does not necessarily mean the child can read independently at a third-grade level. Its example is a fifth grader with a GE of 7.6, who has performed as well as a typical seventh grader 60% of the way through the year; it only shows the child's reading is well above average for fifth grade. The conversion from scaled score to GE is a published table in the technical manual, and the 10% steps within a grade are interpolated, because the norms rest on fall and spring data only.

Reading the two tables together gives a result that surprises many parents. In grade 3 the spring benchmark (40th percentile, 958) falls on the GE 3.4 row of Renaissance's conversion table, and the spring 50th percentile (978) is GE 3.9. So a child can have a grade equivalent below the current grade number and still be At/Above Benchmark, because the benchmark is a percentile rule, not a grade-level rule. That reading is ours, from two published tables.

What changed with the 2024 norms?

Renaissance says Star Reading norms have been updated four times since 2008, in 2014, 2017, 2022 and 2024. The 2024 norms use test data from 6,405,124 students in 22,978 schools across the 50 states and the District of Columbia, tested between 1 August 2022 and 30 June 2023, weighted by region, district socioeconomic status and district size. They went live in the 2024-25 school year. In its July 2024 announcement Renaissance wrote that scores had declined overall in Star Early Literacy, Star Reading and Star Math, so educators using school or district benchmarks would likely see fewer students classified as needing intervention and more at or above benchmark. State benchmarks were not affected, because they rest on linking studies with state tests.

The effect shows in the numbers. A Renaissance threshold table hosted by Nebraska's education department for 2023-24, which does not state its norm year, puts the grade 3 fall 40th percentile at 940; the 2024-norm table puts it at 921. The same scaled score therefore earns a higher percentile than it used to. We found no new English norms for 2026: the Back-to-School 2026 notes (10 July 2026) mention only updated linking studies for select states, and Renaissance says norms are typically refreshed every three to five years. The technical manual we read is dated June 2026 and still describes the 2024 norms as current.

Is Star Reading an IQ test?

No. Renaissance describes it as an assessment of reading achievement and comprehension, and its technical manual does not use the words IQ, intelligence, CogAT or WISC. The evidence it gives for validity is correlation with other reading tests: across 454 concurrent analyses covering more than 1.26 million students, the within-grade average correlations for grades 1 to 6 ran from .74 to .80, with an overall weighted average of .77, against tests including NWEA MAP, the Iowa Test of Basic Skills, DIBELS oral reading fluency, the Stanford Achievement Test and state tests. Its reported split-half reliability is .98. That is high for 34 questions and reflects the adaptive design, but it is reliability of a reading score, not evidence about general ability. The maths counterpart, with Renaissance's full table for kindergarten to grade 12, is Star Math scores by grade level.

The only link we found between Star Reading and a cognitive-ability test is a blog post by MHS, which publishes the Naglieri tests, on an Oregon sample of grades 2 to 6 with 119 to 130 students. It reports corrected correlations of .30 to .55, and .50 for the total score. That is a vendor's summary, not a peer-reviewed paper, and we could not read its raw table, so we treat it as a hint. A reading score and an ability score overlap but are not the same, as our guide to achievement tests versus IQ tests sets out. Gifted programmes that use CogAT or NNAT scores are covered in our CogAT and NNAT guide.

If you only want to see where a percentile sits on the IQ scale, the arithmetic is simple, using a mean of 100 and a standard deviation of 15. The 10th percentile is 81, the 25th is 90, the 40th is 96, the 50th is 100, the 75th is 110 and the 90th is 119. Those figures restate a ranking; they do not turn a reading score into an IQ, because the norm group is children of the same grade taking a reading test. For the method, see our guide to IQ z-scores and the IQ percentile calculator.

What to ask when you read a Star Reading report

• Which test window: the same scaled score is a higher percentile in fall than in spring
• Which cut lines your district uses: Renaissance's defaults are 10, 25 and 40, and some districts change them
• Scaled score trend: follow the scaled score across windows, not the grade equivalent
• Growth: compare the gain with the median gain for the grade (96 points from fall to spring in grade 1, 38 in grade 3)
• Norm year: percentiles from different norm years are not strictly comparable

For a school test that does report on the IQ-style scale, see our guide to the Iowa Assessments. To see where a score of your own lands, take the IQ Metrics test and read it against the IQ bell curve.
