## What does stanine mean in test scores?

Stanine scores are derived from a national norm reference sample. A stanine is a score from 1 to 9 with a. stanine of 9 indicating a very high level of general ability relative to the whole norm reference group, and. a stanine of 1 indicating a very low relative achievement.

## What is stanine and percentile?

Stanine. Stanine(STAndard NINE) is a method of scaling test scores on a nine-point standard scale with a mean of five (5) and a standard deviation of two (2). Test scores are scaled to stanine scores using the following algorithm: Rank results from lowest to highest.

**How is stanine calculated?**

Calculation of Stanine Scores

- The first 4% of ranked scores (raw scores 351-354) will be given a stanine score of 1.
- The next 7% of ranked scores (raw scores 356-365) will be given a stanine score of 2.
- The next 12% of ranked scores (raw scores 366-384) will be given a stanine score of 3.

### What is a stanine of 8?

Stanine scores of 7 or 8 are usually interpreted as indicating “above average” performance. And a stanine score of 9 is normally considered to reflect “outstanding” performance, for that’s the highest score one can get.

### How do you explain stanine score to parents?

A stanine is a score on a nine-unit scale from 1 to 9, where a score of 5 describes average performance. The highest stanine is 9; the lowest is 1. Stanines are based on the pattern of scores described earlier. Except for 1 and 9, they divide the baseline into equal amounts of the characteristic being measured.

**How are percentile ranks and stanines used with standardized test scores?**

The stanine scale is a normalized standard score scale consisting of nine broad levels designated by the numbers one through nine. A percentile rank indicates the percentage of students in the same age group whose scores fall below the score obtained by a particular student.

## What is the highest stanine?

9

The namestanine comes from “standard nine.” There are only 9 possible staninescores, whole numbers from 1 (lowest) to 9 (highest). Relating stanines to thenormal curve, each stanine score represents a wide band of raw scores andpercentile ranks.

## How do you find stanine from z-score?

Procedure to find stanine scores/convert data in stanine scores:

- Find the mean µ of the data.
- Calculate the standard deviation σ for the given data.
- Covert the data into Z scores using the formula, Z=(X-µ)/σ
- Replace the Z score value by the corresponding stanine score by using the below table.

**How do you explain stanines to parents?**

### How do you explain grade level equivalent scores to parents?

Simply put, an age equivalent is a comparison of your child’s performance compared to age groups whose average scores are in the same range. For example, if your 9-year-old child scores a 42 raw score on a test, and that score is average for 8-year-olds, their age equivalent score would be 8.

### What do percentile ranks mean?

A percentile rank indicates how well a student performed in comparison to the students in the specific norm group, for example, in the same grade and subject. A student’s percentile rank indicates that the student scored as well as, or better than, the percent of students in the norm group.

**How do you interpret percentile rank?**

Percentile ranks are often expressed as a number between 1 and 99, with 50 being the average. So if a student scored a percentile rank of 87, it would mean that they performed better than 87% of the other students in his norm group.
