Decoding the GL Assessment (PTM): What Does "Stanine 5" Actually Mean?
The Data Guide

Decoding GL Reports:
What is "Stanine 5"?

You just received the "PTM Report" from school. It's full of graphs and numbers like "SAS 100" and "Stanine 5." Is this good? Bad? We decode the jargon so you know exactly where your child stands.

It's NOT a Percentage

The biggest mistake parents make is thinking a score of 100 means "Perfect." In GL Assessments, 100 is the Standard Age Score (SAS). It literally means "Average." If your child scores 100, they are performing exactly where they should be for their age.

The Cheat Sheet: What the Numbers Mean

Dubai schools use two main numbers: SAS (Precision) and Stanine (Broad Bands). Here is how to read them:

Stanine SAS Score Range What it Actually Means
1 - 3 Below 88 Below Average. Likely struggling with core concepts. May need intervention.
4 - 6 89 - 111 Average. This is the "Sweet Spot" where 60% of students sit. Stanine 5 is exact average.
7 - 9 112 - 141 Above Average. High achievers. Stanine 9 represents the top 4% of students.

The "Dubai Skew" (Why Average Feels Low)

Here is the reality check: Stanine 5 (SAS 100) is globally perfectly fine.

However, in competitive Dubai private schools (like DESS, JESS, or DC), the school average is often significantly higher (SAS 110-115). This means a child with a "Global Average" score might be in the bottom set in their specific Dubai school.

The "Invisible" Ceiling

If your child is stuck in Stanine 4/5 (Average), they are often placed in the middle sets. While fine, this can limit their access to "Higher Tier" topics in secondary school. Moving from Stanine 5 to Stanine 7 requires mastering Reasoning questions, not just arithmetic.

The "Potential" Gap

Compare their CAT4 Quantitative Score (Potential) with their GL Math Score (Performance).
If CAT4 is High (120) but GL is Low (95), they are underperforming. This is the biggest red flag that a tutor needs to address.

Don't Just "File" The Report

Look at the "Topic Breakdown" section at the end of the PDF. It will tell you exactly where the gaps are (e.g., Geometry or Mental Math).
