In this paper I make a contribution to three distinct, but deeply interwoven subjects. Firstly, I argue that, at the level of ideal theory, the distribution of educational goods should follow a sufficientarian pattern and that the evaluative space of children's advantage should be inspired by the capability approach (although with an important twist). Secondly, the paper is delving into the more policy-oriented debates on the desirability of school choice. I argue that, given the non-ideal circumstances in which decision makers have to act, giving parents the opportunity to choose the school for their children is a "sine qua non" condition for even approaching the ideals of sufficientarian justice. Lastly, I move the discussion on more empirical grounds, advancing a criticism of the Romanian educational legislation. I argue that the sufficiency-constrained school choice system that I envision could solve some of the problems that the Romanian educational system faces today.
