This study reports the effect of a treatment tool called "Babudoh's comprehension therapy" in enhancing the comprehension and writing skills of 10 junior secondary school students with congenital and profound hearing impairment in Plateau State, Nigeria. The study adopted the single group pretest-posttest quasi-experimental research design where the students were subjected to a pretest which was made up of five different tests, a treatment (the Babudoh's Comprehension Therapy), and a post treatment. The students were exposed to twelve weeks of treatment using story books, which entailed reading, vocabulary development, retellings (written and in sign language), comprehension exercises, drama, and the production of specific activities. Total communication was the medium of instruction, and the data collected were analyzed using simple percentages, means and the t-test for dependent samples. The study revealed that the students' sight vocabulary and comprehension improved considerably after treatment. The student' writing skills were also enhanced.
