Language is a complex phenomenon whether it counts in speaking or writing. Teaching and learning English language is much demanded in today’s globalization era. The increasing need of English language learning has demanded English language teaching around the globe. Therefore, the demand for language learning needs a tremendous quality in language teaching materials and resources. In current years, language learning has been perceived from a special perspective; it can be viewed as the communication between users and the learner of the language. The aim of the study is to determine the factors that deter teachers to implement communicative approach in their teaching. Researchers and practitioners have considered communicative competence as an ideal teaching approach (Berns, 1990). However, public sector colleges in Pakistan rely on Grammar Translation Method (GTM). Though students have good understanding of the language skills such as vocabulary, grammar and reading but research still have shown low proficiency when their speaking skills are tested. Therefore, in order to overcome this default in language proficiency, many teachers are supposed to adopt communicative language teaching methodology in their teaching. The study findings shed light on the factors which always deter teachers in the implementation of CLT and it is believed by the teachers that CLT should be followed at public sector colleges since it is one of the most effective methods of language teaching and learning. English language teaching and learning can be learnt meaningfully, if the aspects like phonetics, phonology, morphology, syntax and semantics will be instilled or implemented properly.
