I'm in a similar situation. While I am secure in my position, and have received positive performance feedback, I am still keeping my MBA intentions quiet from the partners. It sounds as though the partnership has the intention of promoting me to management this next year, so I have somewhat of a dilemma. On one hand, if I find out I have been accepted to one of my target MBA programs in Dec./Jan., I could give my employer advanced notice that I will be leaving in August, hence allowing them to promote somebody who may stick around longer. On the other hand, if I wait until after I get promoted, I would essentially have to give notice within weeks of being promoted to manager. But, management would probably look better when recruiting during school...I'm not sure what I will do if put in that situation.
