    Hi GCC 

    You may try below measures.

    Step1 = COUNTROWS(FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])))
    Step3_rank = RANKX(FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])),CALCULATE(SUM('Table'[cum_total_tariff_pts])),,ASC,Skip)
    Lowest 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]<=[Step1]*0.2))
    Middle 60% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]<=[Step1]*0.2+[Step1]*0.6&&[Step3_rank]>[Step1]*0.2))
    Top 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]>[Step1]*0.2+[Step1]*0.6))

Hi Cherie,

Thank you very much for creating this code for me and it works just perfect as long as you're working with just one year. I have data for numerous years and numerous schools within these years. I need to be able to calulate the lowest 20% average, mid 60% average and top 20% average for each school within each year. Could you help me with creating this code? I've tried using your code with slicers but it didn't work.

Thanks once again for your help.

Regards

Geoff
