    This works for me.

    SELECT ID,

    CASE WHEN Category IN( 'Art', 'PE') THEN 'Non Educational' ELSE Category END Category,

    DATEADD( dd, -1, DATEADD(wk, DATEDIFF(wk,0,Date), 0)) Week,

    SUM(Hours) Total_Hours

    FROM Attendance

    GROUP BY ID,

    CASE WHEN Category IN( 'Art', 'PE') THEN 'Non Educational' ELSE Category END ,

    DATEADD( dd, -1, DATEADD(wk, DATEDIFF(wk,0,Date), 0))

    However, I'm not sure about your second requirement. It seems that you might need a running total calculation. For information on this article Solving the Running Total and Ordinal Rank Problems[/url]
