Validating Point In Time Assessments

By September 10, 2019 No Comments

I’ve previously written about perfecting point in time assessments, arguing that if a pupil is judged to be working at above or below expectations it is important to be able to measure how far away from ‘average’ he or she is. Target Tracker’s relationship between its PITA (point in time assessment) system and ‘Steps’ (linear assessment) system provides this facility.

It is important that this relationship is validated and to do this I have correlated how pupils’ working at age related expectations have performed in end of reception and Key Stage 1 and 2 statutory assessments. These results are presented below.

Methodology

Over the summer teacher assessments from all Target Tracker schools were anonymously collected and collated. Only pupils who had an explicit summer 2 assessment and statutory assessments were included. For reception this was approximately 69,000 pupils, Key Stage 1 56,000 pupils and in Key Stage 2 49,000.

The attainment of pupils judged as ‘on-track’ or above were analysed. In Target Tracker terms this means those judged as ‘at risk of working below age related expectation’ (light pink, w+ in the appropriate band in summer 2).

For the first time the attainment of those working above age related expectations (light green, s+ in the appropriate band in summer 2) was also analysed at Key Stages 1 and 2.

Reception

The majority of pupils judged as ‘on-track’ achieved the expected standard or above at the end of reception.

Key Stage 1

The vast majority of pupils who were assessed using Target Tracker as being on-track achieved the expected standard or above at the end of Key Stage 1:

95% 93% 95%

Percentage of pupils judged as on track who achieved expected standard or above in end of KS1 statutory assessments.

Most pupils who were assessed as working above age related expectations achieved greater depth.

Percentage of pupils judged as working above age related expectation who achieved greater depth in end of KS1 statutory assessments.

Key Stage 2

For the writing teacher assessment judgement, 96% of pupils who were judged as working at least minimum on-track expectations achieved the expected standard or above.

For the reading, GPS and maths tests once again the vast majority of pupils who were assessed using Target Tracker as being on-track achieved at least 100 in the test.

Reading GPS Maths
88% 92% 94%

Percentage of pupils judged as on track who scored at least 100 in end of KS2 statutory assessments.

 For the writing teacher assessment judgement, 90% of pupils who were judged as working at above age related expectations achieved greater depth.

Most pupils who were assessed as working above age related expectations got a standardised score of 110 or above.

Reading GPS Maths
71% 84% 79%

Percentage of pupils judged as working above age related expectation who achieved a standardised score of 110 or above in end of KS2 statutory assessments.

Conclusion

There is a high correlation between the Target Tracker age related expectations and attainment in the end of reception, KS1 and 2 statutory assessments.

Therefore we can have confidence that the Target Tracker point in time assessment system is used by schools to make accurate judgements of which pupils are on track and provides a very good indication of performance.

I hope you’ve found this analysis useful moving in to the new term, remember our Target Tracker helpline and online support is available for any additional support you may need.
