Among the several measures being adopted to upgrade the level of education in Israel is the policy of maintaining an equal achievement level in all public high schools. Short-run allocation of elementary school graduates to schools is therefore needed. This paper presents a spatial allocation procedure which aims at improving achievement equality simultaneously with upgrading accessibility to schools. The procedure allows the mutual effect of these two factors to be varied, as well as the measurement of the real-world meaning of such variations. The advantages of the proposed procedure in comparison with the common linear programming model used in spatial planning of school districts are discussed. Allocation patterns generated for the city of Beer Sheva illustrate its use.
