Studying the Impact of Inputs on the Output of Middle School Education System

This research aims at studying the impact of inputs on the output of middle school education system in Iran’s provinces. Hence, first the output of lower secondary level education system in provinces of Iran is calculated on the basis of indicators approved by International Institute for Educational Planning & UNESCO Institute for Statistics. The results showed that provinces Such as Sistan & Balochestan, Khozestan, Khorasan, Kohkiloyeh & Boyerahmad, have the lowest educational output while places such as city of Tehran, Yazd, and Isfahan provinces have the highest educational output. in order to study the factors influencing educational output of middle school education system in all provinces four hypotheses were proposed. The results of running these hypotheses show that there is a significant negative relationship between pupil-teacher ratio and educational output at the level of p < 0.01. And there is a significant positive relationship between pupil-class ratio and educational output at the level of p < 0.05. Thus, the relationship between input and output of middle school education system in provinces of Iran could be formulated as follows:
The middle school Educational output = 86.09-0.65 (i.e. pupil-teacher ratio in middle school) + 0.54 (i.e. pupil-class ratio in middle school)
The aforementioned relation reveals that provided that all the other conditions are the same, one unit of decrease in the pupil-teacher ratio in middle school will lead to 0.65 unit of increase in educational output of middle school. On the contrary, one unit of increase in the pupil-class ratio in lower secondary level will lead to 0.54 unit of increase in educational output of middle school.
