We have written previously about how the points awarded to the European Computer Driving Licence in school performance tables appeared to be out-of-kilter with other qualifications, given the grades achieved by ECDL entrants in GCSEs they took. And Data Educator has subsequently written more on the topic. (To give it its full title, we’re talking about the BCS Level 2 ECDL Certificate in IT Application Skills.)
In this blogpost we examine the impact it has had on schools’ Progress 8 scores.
In order to do this, we firstly rescale the points awarded to pupils entered for ECDL using the values in the table below. For each ECDL grade, for those pupils who achieved that grade we have calculated the average point score in all GCSEs for which they were entered – these figures are given in the rescaled points column. Clearly there are lots of other ways it could be done.
|Grade||Current points||Rescaled points|
We then recalculate Progress 8 (P8) scores with these rescaled ECDL points. The scatterplot below shows the change in schools’ P8 scores as a result of the rescaling plotted against the percentage of pupils entered for ECDL.
As can be seen, some schools with a high percentage of ECDL entry see a change in their P8 score of almost -0.2. However, the impact for other schools with similar rates is lower, not even changing by -0.1 in some cases. The scores of 123 schools changed by more than 0.15.
Meanwhile P8 scores for schools with zero, or very low, ECDL entry rates tend to increase slightly.
The impact on the numbers of schools below the proposed floor standard of -0.5 is not so great. Of the 294 schools that, based on provisional Key Stage 4 data, are below the floor standard, 20 schools would lift themselves above it if ECDL was rescaled. However, another 26 schools would fall below it.
In summary then, ECDL had a noticeable impact on the P8 scores of a small number of schools in 2016. We would strongly argue in support of greater comparability in performance measures of different subjects and qualifications.
