Yes. Once you hit a certain level in logic (I believe it's 5), you may tutor children to raise their school performance bar. Click on the child sim, then Friendly interactions, then tutor. This is different from the tutor-sim-in-skill interaction that is not included in the Friendly interactions. There are even a few opportunities where you can tutor children for simoleons. The child gets out his homework (even if it's the weekend and he hasn't gotten any homework yet because he hasn't gone to school) and the adult sits down with him and tutors.
