Being purposeful, systematic and carefully implemented, evaluation is a continuous process and it is performed as the very basic part of the program activities to attain data to conclude if there is a need to make changes or eliminations, or accept something in it. Program evaluation is a kind of examination in social research field and it checks the sufficiency of educational programs. The broadest purpose of evaluation is to contribute judgments about the worth of an evaluated program or to point to the value of the program or just a section of it. The evaluators choose an evaluation model among several ones, each of which has its own characteristics or way of approaching the evaluation. One of these models is Four level Evaluation Model by Kirkpatrick. This study was conducted based on the Document Analysis Technique by means of inquiring Kirkpatrick's framework from various sources of academic books and articles. From the analysis, one can conclude that Kirkpatrick's four-level model of program evaluation is one of the mostly employed models by the program evaluators. Besides, this study offers a documented data of how Kirkpatrick's framework that is easy to be implemented functions and what its features are.
