The present study concentrated on inspecting the relationship of assimilation and contentment of general education teachers (GETs) and special education teachers (SETs) with the implementation of single national curriculum (SNC). The main concern of the present study was to explore the effect of age on assimilation and contentment amidst GETs and SETs. Selfdeveloped research instrument was used to measure the phenomenon of assimilation and contentment. Cronbach alpha value was estimated 0.81 and viewed as adequate for the present research. The sample size was comprised of (N=290) GETs and SETs, males and females. GETs (n=145) and SETs (n=145) picked-out from different cities of Punjab, Pakistan. Pearson Product Moment Correlation and t-test were employed to test the hypotheses. The obtained results indicated a significant positive correlation (r= .81, significant at p 0.01) in assimilation and contentment. Later, the researchers made recommendations at the end.
