creases in all private schools providing education to handicapped children is in reality a rule or regulation has merit. A “rule” is defined in section 101-a (suhd 1, par b) of the Executive Law. A rule that is not formally adopted pursuant to the procedural requirements of the New York State Constitution and the Executive Law is invalid (NY Const, art IV, § 8; Executive Law, § 101-a, suhd 6). In the instant case, the ceiling was imposed across-the-board and without respect to the needs of the individual schools involved. The fact that the Commissioner of Education at one point was willing to raise the ceiling to 8% does not indicate a “flexibility” which would render the across-the-board policy a mere guideline as claimed. In our view, the ceiling is therefore invalid for failure to comply with procedural requirements. The Commissioner of Education, although possessed of the power to limit reimbursable tuition rates, cannot do so in an arbitrary or capricious manner (see
Carlisle v Bennett, 268 NY 212 ;
Matter ofWonderly v Division ofN. Y. State Police, 80 AD2d 974 ). The ceiling in the case at bar is arbitrary because it is based on the salary of all teachers and not limited to teachers of the handicapped. The market conditions for teachers of the handicapped differ markedly from those for other teachers. Furthermore, the ceiling will not accomplish the apparent economic saving desired by the Commissioner of Education. To the contrary, it has created an anomolous situation where newly hired staff may be paid at higher market salaries than retained experienced staff whose salary increases are subject to the ceiling. Petitioners’ contention that since the tuition rate was not adopted by May 1, they were entitled to assume that the commissioner had impliedly consented to their proposed budgets is rejected. Submitted budgets only establish provisional tuition rates which, as petitioners should have realized, must be reviewed by a number of persons before they are finalized. Tuition rates established by the commissioner are subject to the approval of the director of the budget (Education Law, § 4405, subd 3, par e) and may be changed after a State audit (8 NYCRR 200.9 [fl; see
Dubendorf v New York State Educ. Dept., 97 Mise 2d 382, 396,
supra). The estoppel doctrine therefore has no application in this case. Finally, we conclude that the Commissioner of Education and not the Commissioner of Social Services is the proper authority to determine allowable tuition reimbursement rates for petitioner Summit School for the school year 1979-1980 and thereafter. There is no dispute over the fact that Summit School provides services under article 89 of the Education Law. This issue is one of law, namely, the correct interpretation of the statute (Education Law, § 4405). Special Term improperly ruled that the request was premature. Administrative remedies in such cases need not be exhausted (see
Matter ofDe Vito v Nyquist, 56 AD2d 159 ,161, affd
43 NY2d 681 ). Judgment reversed, on the law, without costs, petition granted, and matter remitted to the Commissioner of Education for recomputation of the petitioners’ reimbursement tuition rates for the 1979-1980 school year. Sweeney, J. P., Main, Mikoll and Yesawich, Jr., JJ., concur.
