In education, essay is considered as the best tool to evaluate student’s high order thinking and understanding. In the other hand, manual processing and grading essay answers by a teacher need much time and tending to subjectivity grading. Meanwhile automatic essay grading in e-learning system find the difficulties in comparing model or key answer to student’s answer because student’s can answer the question with so various way. That means a right answer also can be so various, while they have same semantic meaning. This paper proposed automatically score the essay using Latent Semantic Analysis. But before the texts being scored, they will be pre-processed using stop words removal and synonym checking. Calibration process implemented for dealing with the various possible right answer. Implementation of this approach using Java Programming Language and WordNet as lexical database that needed to search the synonyms of every given words. The accuracy obtained by this method is 54.9289%.
