The methodological process implied the construction of efficient indexes, evaluated through the adjust grade of the budget variable. It was verified that: a) the variable inflation is not the only determining of the municipal planning adjusting; b) It exists, in the municipal technical staff, lack and deficiency about the planning and the discipline (technical) budget; c) The absence of a formal and established process that could evaluate the budget proposals, in the discussion and approval of the laws, considering this a legislative responsibility. Therefore, is concluded that the legislators, mainly in the period of price establishment, were not efficient considering the exercise of their jobs, judgment, discussion and approval of the budget laws in the cities of the Medium Plateau Region of the state of Rio Grande do Sul, since they permitted the systematic superevaluation budget, which proposed the generation of a series of deficits
