Accessing 4Matrix from Outside School

There are several ways in which this can be achieved, and we have put together a document to help users decide on which option is best for their school. 

You can download the document from this link: https://www.4matrix.com/news/remoteaccess

In-light of the current situation, we are extending the free-use period of 4Matrix Infinity for all schools until September 2020.


Import Fix

There is a fix available for an error which occurs when attempting to import data via a spreadsheet into an existing series in which results or custom field data has already been imported.

 What do the Difference and Variance columns mean in Series Comparison?

Solution

KS4

Difference: The direction of the 'spread' of results expressed in points. Sum of all points differences for all pupils divided by number of pupils. A difference of 6 is 1 GCSE grade, and so a difference of 3 is +0.5 of a grade in a GCSE subject.

Because this tool works in QCA points, the difference between a 5 and a 6 in a GCSE number grade qualification will show as 6.  This will correct itself over time as we look to replace the underlying the currency across all tools to 9-1 in early 2017.

Variance: The 'spread' of results expressed in points  - this figure will always be positive. 2 pupils, 1 moving from a C to an A and the other B to a C are expressed as differences of 12 and 6. Divide total by number of pupils. 18/2 = 9. This indicates a variance of 1.5 grades in a GCSE subject (where the difference between each grade is 6 points, except from a U to a G which is 16)

 

KS5 (2016 onwards)

Variance: The 'spread' of results expressed in points  - this figure will always be positive. 2 pupils, 1 moving from a C to an A and the other B to a C are expressed as differences of 20 and 10. Divide total by number of pupils. 30/2 = 15. This indicates a variance of 1.5 grades in an A Level subject.

 

Difference: The direction of the 'spread' of results expressed in points. Sum of all points differences for all pupils divided by number of pupils. Using example above, 20 + -10 = 10, /2 = 5. 5 indicates a difference of +0.5 of a grade in an A Level subject.
