This will firstly order the results by LrnParentInvolvment.ParentInvolvmentID Then starts to assign an incremental row number to them starting from 1.

You may see sometimes PARTITION BY before order by, then it will : firstly group them by the columns specified in PARTITION BY then orders each group by ORDER BY columns then starts numbering each group separately.

Hope it helps.
