This grading scales dataset puts 36 grading systems from 19 countries in one table, one row per grade: the marks or percent for each grade, its grade points where the system has them, the source the rule comes from and the day GradeCat last checked it. It is free to download and reuse under CC BY 4.0.

267 grades in all. Last updated 10 November 2026.
What is in the dataset
Each system comes from the same sourced record as its GradeCat page, where the full table sits next to its calculators. Schools and universities in the same country can use other scales, so the files' scope column says who each system is for.
The columns
The CSV has one line per grade, with a header line, in UTF-8. The JSON holds the same grades under each system, with each source listed with its publisher, section and the day it was opened.
| Column | What it holds |
|---|---|
system_id | A short, stable id for the grading system |
country_code | ISO 3166-1 two-letter code (GB for the United Kingdom) |
country | Country name |
system | The grading system, exam or institution |
scope | Who and what the system applies to |
grade | The grade, class or level as the source prints it |
marks | The marks or percent for the grade, as printed; empty when the source gives none |
marks_min | The lowest mark in the grade, as a number; empty when the source gives none |
scale | What the marks measure, such as percent or Notenpunkte (0 to 15) |
points | Grade points, CAO points or a grade number, as printed |
points_name | What the points column holds for this system |
result | Pass, fail or credit, only where the source says so |
meaning | The grade's name or description in the source |
note | How to read the system, from its record |
checked_on | The day GradeCat last checked the rule against its sources (YYYY-MM-DD) |
sources | Each source as publisher, title and section, separated by " | " |
source_urls | The source addresses, in the same order, separated by spaces |
gradecat_page | The GradeCat page that shows the system, with its calculators |
What the dataset leaves out
- Any rule GradeCat could not confirm against a primary source. The country pages list those as not verified.
- Kenya: KNEC prints percentages for the overall KCSE grade, not for each subject, so its table waits until GradeCat can say plainly how to read it.
- Singapore: Singapore Polytechnic's marks for the grades below A are not confirmed.
- Hong Kong: the universities' pages give no marks table.
- Mexico, Indonesia and Brazil: their rules are averages and weights rather than grade tables. Their calculators are on their country pages.
How to reuse and credit it
The dataset is licensed under the Creative Commons Attribution 4.0 licence (CC BY 4.0). You may copy it, share it, change it and build on it, in an app or on a website too, as long as you credit GradeCat, link to this page and say what you changed. One way to credit it:

The grading rules come from the laws, exam boards and universities each row names, and their own documents keep their own terms. A school's own rules always win, so check the source of the system you use.
How it is kept up to date
The files are built from the same records as GradeCat's grading scale pages and printable charts, so they change when a page changes, and each system keeps the day its rule was last checked. If a row looks wrong, tell us on the contact page.
