PowerBI report - The Ofsted Quality Dashboard contains achievement rates data by programme. This can be filtered by qualification/standard or framework and by planned end year. The tab that is probably most useful is Delivery by Qualification which then gives a further split by age/disability/ethnicity and gender, as shown below.
Achievement Grade for completed learners is available in the Funding Dashboard Power BI report -> Tab 'Learner Funding Data' -> Column 'Grade'.
While there is no specific retention percentage, this could be easily calculated from the learner count in PowerBI report - The Ofsted Quality Dashboard, tab Delivery by Qualification.
