		abstract={The implementation of Accelerated Learning Approach to increase students achievement  is to know the students achievement in SMA Negeri 1 Berastagi. The population was all the students at second level in SMA Negeri 1 Berastagi. The students were divided into two groups one was called experimental  class  in class XI IPA-5 and control class  in class XI IPA-3  based on purposive  sampling techniques. The kind of this research is experimental research. The first time, pre-test will be given to experimental class and control class. Then, give the treatment. In experimental class  was used  accelerated learning approach and in control class  was use conventional learning. The last, giving post test for each of class.  Based on the result in experimental class  was obtained the average of pre-test score 30.67  and post test score 56.67. In control class  was obtained the average of pre-test score 30.50  and post test score 47.67. Data must be normal and homogeny. The hypothesis test by using sig 2- tailed. Criterion of hypothesis is received Ha if sig < 0.05. From the result is obtained all the sig is 0.00 < 0.05 . Hypothesis alternative (Ha) is received and Hypothesis null (Ho) is rejected. It proved that Students achievement with accelerated learning approach  is higher than conventional learning type. Increasing the students achievement was calculated by using normalized gain and the percentages gain in experimental class  are 42 % and percentages gain in control class  are 27 % .}
