Summary, etc. The ternary Se<sub>79</sub>Te<sub>20</sub>Pb<sub>1 </sub>chalcogenide glass is prepared using melt quenching technique. Differential scanning calorimetry technique (DSC) is used to investigate the kinetics of crystallization of amorphous-crystallization (a-c) phase transformation under non-isothermal conditions at three different heating rates; 5, 10 and 15° C min<sup>-1</sup>. The variation of crystallized activation energy (<em>E<sub>c</sub></em>) with crystallized fraction (<em>ϰ</em>) and hence, with temperature (<em>T</em>) is investigated using five iso-conversional methods namely KAS, OFW, Friedman, Tang and Chen and Starink. It is found that <em>E<sub>c</sub></em> is not constant but vary with <em>ϰ</em> as well as <em>T</em>. Thus, the iso-conversional analysis of investigated glass indicates that the assumption of constant <em>E<sub>c</sub></em> is not appropriate
