Partial Engine Power on Takeoff

I'm curious how other people have handled their experiences when they had partial power on takeoff. We all train to complete fail en route, which is nothing like right after takeoff. The ACS is failing students. A partial power scenario may lead someone on since they are thinking about complete fail.

Would you do a flow? Immediately turn around? Small pattern? I'm more or less curious to hear others experiences. Wanting to make myself and others better! Thank you!
