<![CDATA[The ability of students to understand the learning material is important. When students are able to understand the material given by the teacher, then they can apply the knowledge theoretically or in action. A simple way to check students' understanding or ability is through written assessments and student skills. This research was appointed to find out how far the students' ability in understanding grammar, in this case is the Simple Future Tense. This study uses quantitative as a research design and descriptive as research methodology. This study took a population of tenth graders at SMA 3 Jambi City in the 2021/2022 academic year and the sample was students in class X MIPA 6 in the 2021/2022 academic year. This study uses a test given to the respondents as a research instrument, then the results of the test are assessed and analyzed. The average value of the test obtained is 56.27. On the other hand, the value of the standard deviation obtained is 33.017. As a result, 11 respondents from the sample received the predicate "very good". 9 respondents received the “poor” predicate, followed by 5 respondents received the “very poor” predicate. 3 respondents received the predicate "good" and 2 respondents received the predicate "moderate". However, it should be noted that many errors occurred in the second part of the test where many of the respondents made a mistake in arranging one complete sentence with a percentage of 57.78% incorrect answers. This is inversely proportional to the test in the multiple-choice section, where the percentage of correct answers reaches 77.33%. In addition, although 11 respondents received a very good predicate, the collective average value shown is not a satisfactory result and is still categorized as "moderate". The difference between the mean and standard deviation shows that the data obtained are heterogeneous with most of them being below the sample mean.]]>
