The problem stemmed from that fact this document, despite its importance and efective role in language education yet, it is not used as a teaching material that can help teachers to enhance language teaching and language learning. The samples have purposively drawn from supervisors’ population gathering in the Sudan School Certifcate Marking Centre in Khartoum during 2021-2022. An interview is designed by the researchers and directly distributed to supervisors. Out of the whole population of markers who were more than 500 people in the centre, the researchers were only able to reach 13 participants who deemed to have used this document in EFL teaching environment. The research came with very disappointing results that most of the supervisors admitted that the TG has disappeared a long time ago from the teaching sphere. But they all agreed about the importance of the TG in boosting language education as well as helping in controlling the whole educational practice of teachers in schools. They almost all agreed that the TG is one of the tricks that can help teachers plan their lessons and create productive and efective educational environment. The researchers recommended some points to make this document efective. Some suggestions for further studies have been provided for further investigators in this feld. The results of the research can be generalized to other disciplines in similar context and similar environment, so the study can be duplicated to serve educational objectives in similar situation.
