A pre–experimental study was conducted on 50 mothers  to assess the effectiveness of structured teaching module on their knowledge regarding maternal and child health services (MCH) with the objectives of assessing the knowledge of mothers regarding MCH services, evaluate the effectiveness of structured teaching module in term of gains in levels of knowledge and find out the association between the knowledge of mothers regarding utilization of MCH services and selected demographic variables such as age in years, gravida , frequency of MCH clinics attended ,sources of information regarding MCH clinics.  The conceptual model adopted for the study was Conceptual frame work based on General System Model of Von Bertalanffy.

           One group pretest post test design, with an evaluative approach was used for the study. The structured knowledge  questionnaire which consists of 40 questions regarding MCH services . The minimum score of the knowledge assessment questionnaire was 0 and maximum score was 40.

           The study findings revealed that the mean post–test knowledge score was apparently higher (38.74) when compared to the mean pre–test knowledge score (29.54). The score of pre–test (SD=2.19) was more dispersed than the scores of post–test (SD=0.84). Findings showed that the  mean post test knowledge scores of mothers were significantly higher than that of their mean pre–test score. Thus the knowledge of mothers regarding MCH services was improved. Effectiveness of structured teaching module was tested by using paired‘t’ test. The calculated  ‘t’ value of pre–test knowledge score (t₄₉=31.29, P < 0.05) is higher than the table value. Therefore, it can be concluded that the difference in the mean observed was a true  difference  and the teaching module on knowledge regarding utilization of MCH services was effective.

There was a significant association between frequency of attended MCH clinics, but no significant association was observed between age in year, gravida, sources of information regarding MCH services.
