This study deals with the effect of Numbered Heads Together Technique on students’ achievement in reading descriptive text. The population of the study was the 2015/2016 academic year on the first semester of grade X students of SMA Swasta Yayasan Perguruan Indonesia Membangun Medan. The samples consistst of two classes, namely X IPS 1 and X IPS 2, with the total was 60 students selected by applying random sampling. The sample was divided into two groups, i.e. Experimental group (X IPS 2) taught by applying Numbered Heads Together Technique and the control group (X IPS 1) taught without applying that technique. The data of this research were taken from the students’ score of reading descriptive text test. The calculation showed that the coefficient of the test was 0.65. It shows that the test is reliable and the reliability is substantial. There were two data used in this research. They were pre-test and post-test. The data were analyzed by using t-test formula to show the effect of applying Numbered Heads Together Technique on students’ achievement in reading descriptive text. After analyzing the data, the finding indicates that t-observed is higher than t-table (5.50 > 2.00) at the level of significance 0.05 with the degree of freedom (df) 58. It means that applying Numbered Heads Together Technique has significantly affected the students’ achievement in reading descriptive text. It implies that Numbered Heads Together Technique is a significant technique for teaching reading descriptive text.
