Overview

This article explains how to fix any potential issues (flagged as Invalid Core Baselines) that Sisra Analytics finds when it checks the KS4 core baselines you import for your KS5 cohorts.  

These warnings won’t stop you from publishing, but they could affect the accuracy of your reports. 

Prerequisites

You must be an administrator.

1. Select DATA.
2. Select Keystage 5.
3. Select cohort.
4. Select KS4 / EAP.
5. Select Core Baselines.
6. Select Core Baselines List.
7. Scan the list for any Invalid Core Baseline warning icons, underneath a student's scores that indicate the points recorded for the baseline that aren’t in the expected range (see the section below for Valid Core Baselines:
8. If any warnings exist:
   1. Either manually update the value:
      
      1. Select the blue pencil icon on the row of the student you want to change.
      2. Enter the points.
      3. Select Save.

Valid Core Baselines

The following are valid Core Baseline ranges:

1. KS4 APS GCSE / KS4 APS All - These baselines will accept appropriate average Attainment 8 points values between 0 and 11 (up to 13 decimal places).
2. Prior English / Prior Maths - These baselines will accept the appropriate challenge points for the cohort year you’re working with, which you can see in the table below:

   Valid English Challenge Points (2019)		Valid English Challenge Points (2020 Onwards)		Valid Maths Challenge Points (2019)		Valid Maths Challenge Points (2020 Onwards)
   8		9		8		9
   7.7		8.5		7.7		8.5
   7		8		7		8
   6.3		7		6.3		7
   6		6		6		6
   5.7		5.5		5.7		5.5
   5		5		5		5
   4		4		4		4
   3		3.5		3		3.5
   2.5		3		2.5		3
   2		2		2		2
   1.5		1.75		1.7		1.75
   1		1.5		1.5		1.5
   0.4		1.25		1		1.25
   0		1		0.8		1
   -		0.75		0.4		0.8
   -		0.5		0		0.75
   -		0.25		-		0.5
   -		0		-		0.25
   -		-		-		0

   The tables are displayed independently of each other and should not be used for comparative purposes; for example, challenge points of 5.7 in 2019 do not correspond to challenge points of 5.5 in 2020.
