Here are the best and worst-performing secondary schools in the Portsmouth area

The results, released by the Department for Education, indicate that students attending Portsmouth state schools have on average attained lower Progress 8 scores than last year.

Progress 8 was brought in to judge schools on student progress rather than outcome.

A Progress 8 score is calculated by each subject being given a numerical value for the eight subjects being taken.

Student performance is then calculated by comparing national outcomes of students of the same pre-assessed academic ability.

Students in Portsmouth scored an average Progress 8 score of -0.33 compared to -0.14 in the previous year.

The score indicates that on average Portsmouth pupils attained roughly a third of a grade lower than comparable students nationally.

The city's Progress 8 scores in mathematics and English have fallen by more than double that of 2017 with English scores decreasing from -0.05 to -0.22 and from -0.05 to -0.17 in mathematics.

Hampshire Local Authority has seen their average Progress 8 score rise from -0.14 to -0.09. 

Understanding how your child's school performed

In addition to changing the parameters by which schools assess students the new system has also brought in a whole new format for parents to understand the performance of their children and their schools.

Ultimately a  Progress 8 score of 0 indicates a student has made the same amount of progress, on average, as students with the same Year 7 starting point nationally.

A positive reading would reflect better than average progress and a negative reading would indicate below average progress. Up to -0.25 students are still categorised as having made expected progress. Schools with a progress score of between -0.25 and -0.5 would be classed as '˜coasting' therefore be a potential concern.

The government's minimum required '˜floor target' is -0.5 which would indicate that on average children were attaining roughly half a grade lower than comparable students nationally.

When calculating a student's Progress 8 score their performance in maths and English are given double weighting to represent the importance of these two key subjects. 

The percentage of students attaining a grade 5 and above in maths and English is still present as a separate indicator of performance.

Under the old system a level 5 would be the equivalent of a high grade C.

How did your child's school perform?

The schools for each area are ranked by their Progress 8 score. Their 2018 score is on the left, and the 2017 score is in the centre. 

The figure on the right is the percentage of pupils who reached at least grade 5 and above in English and Maths.
