The intent of the study was to explore the various decision-making styles practiced by the heads of secondary schools in Punjab and to examine the effects of gender on decision-making styles prevailing amongst the secondary school head teachers in the districts of Sahiwal division, viz. Sahiwal, Okara and Pakpattan. A survey based on the opinions of the teachers working under different decision-making styles was conducted through a rating scale devised for the purpose and was utilized over a sample of 960 teachers. ANOVA and Chi-Square were applied to measure mean score, standard deviation and p-value less or equal to 0.05 was considered as significant. It was found that all the decision-making styles like rational, intuitive, dependent, avoidant and spontaneous were being practiced by the heads regardless any gender discrimination with minor difference. Not a single decision-making style was specific to gender. There was no significant difference in the head teachers' use of decision-making style. Moreover, it was also found that rational decision-making style was the most opted style by both the genders. The only difference which subsists was that the ratio of rational decision-making style was slightly better among females. Therefore, the study recommends that the head teachers should contribute their preference to the rational decision-making style.
