What is the datatype of "completionratetotal" column? If that is already a decimal type, you dont have to manipulate it to get decimals. ROUND function is used to round the value to specific decimals points.
I doubt the completionratetotal is an INT type defined in the table. In this case you need to typecast the completionratetotal's value to decimal by using
CAST(AVG(completionratetotal) as DECIMAL(10,2))
Hope that helps.
