Grammar is an essential part of language. After learning grammar, one can be more alert to the strength, flexibility and variety of the language and thus can be in a better position to use it and evaluate others’ use of it. The students of Bangladesh learn English as their Second language (L2). In case of learning L2, the environment is much different than First language (L1) acquisition. Without knowing the grammatical rules of using English, students will not be able to use it with confidence and perfection. A few studies have been made in Bangladesh to find out the status of English grammar teaching and learning in Bangladeshi schools. English is a compulsory subject in Bangladeshi schools and colleges. Students get enough time and opportunity to learn English for several years. There are some fixed items of grammatical rules to teach students in different educational levels. In the syllabus of grammar, the topics and themes have been introduced as vehicles for practicing the four skills of the language such as listening, speaking, reading and writing. However, the question is whether the students are able to acquire the skills of English language or the teachers are able to teach them properly. Though English is a compulsory subject in Bangladeshi schools and colleges, there is a question whether the students are able to produce correct written production or the teachers are able to teach them grammar properly. The present research is designed to investigate the evaluation of English grammar teaching and learning in the secondary level educational institutions of Bangladesh. The present study is qualitative in nature where the survey approach has been chosen as the methodology of this research. The study has found that lack of awareness and interest for teaching and learning English grammar among teachers and students; use of traditional methods of teaching; lack of quality teachers and lack of teachers’ training are significant reasons for the lack of English grammatical competences of our secondary level students. Effective grammar teaching in a communicative way can be ensured through the right kind of attitude towards its teaching and learning. Introduction of new teaching method can be introduced. Interesting communicative practices should be applied. Moreover, awareness should be created regarding teaching and learning English grammar in an effective communicative method.
