Research demonstrates problems with secondary school English grammar instruction. The study's objectives are to (1) identify the challenges of teaching English grammar to secondary school students, (2) examine ways to improve it, and (3) prioritize solutions. This descriptive study was quantitative. All secondary public school English teachers in Vehari were studied. The researcher randomly sampled. The study used a nine-subscale questionnaire (Alam, 2005). Researchers administered a questionnaire to nearly 150 secondary school teachers during in-person visits.Percentage, mean score, and standard deviation yielded the findings. The survey found that secondary school English teachers dislike teaching grammar since they need a background. In secondary school, English grammar teachers require excellent training. The audio-lingual strategy also worked better for English teachers. Teachers think English grammar is complex. Teacher training may inspire secondary school students to study English grammar and language. This study may aid high school grammar teachers.
