Contractors – Summative and Formative Assessment

I had several contractors in to give me estimates for some changes to my house.  The first one measured the room and left.  The second one measured the room and then spent double that time in asking me questions about the room and the house. I went with the second one because he understood what I wanted and how that fit in with the rest of the house.

I see the first contractor as a summative assessment- get a number and leave.  The second contractor was formative. He had numbers but he needed to know what those numbers meant in terms of what I expected in terms of the room (the end goal) and in terms of the whole house (all the other data from the house). He gave me several suggestions for improvements (getting me from where I am to where I want to be) and let me select the one I felt was the most helpful.

Which type teaching contractor are you- summative or formative?
