The empirical part is based on a research where 100 9th graders from 6 different schools answered questions from a questionnaire regarding English tenses. With the help of questionnaire which had 9 tasks in total, we were able to examine and research to what extent do the Slovenian 9th graders know and successfully use Past Simple and Present Perfect. The questionnaire was created accordingly to the syllabus. The learners were the most successful when dealing with the theoretical part of the questionnaire. Even though they had some problem when choosing the correct tense when dealing with practical tasks, they had a higher success rate when dealing with the tasks that were theoretical. The learners from 9th grade achieved overall positive success rate in all tasks which means that they successfully know, recognize and properly use Past Simple and Present Perfect Tense.[K.
