So for the above score do you recommend any additional programs or are the scores O.K for a first grader.
The link to MAP math percentile charts from  
this thread shows that the math score is in the 83rd-85th percentile.  Is that a problem for you?  Re: after-school programs, Kumon seems like a lot of boring drill to me, but I've only seen some of their workbooks.
ETA: Please read the "Is that a problem" language above as a simple question about whether that percentile is out of line for the specific kid, etc.
