The purpose of the study was to investigate the extend of the learners gain in speaking skill improvement after the use of role playing as part of a language subject in the program. The study used an experimental posttest only design with one group of the participants receiving an intervention, which is role-playing, designed to cultivate English speaking skill necessary for law enforcement. Data were analyzed with percentage, means, and standard deviation.

The test determined whether and to what extent grammatical form and grammatical meaning had an effect on use of English after instruction. The results of the study presented empirical evidence in support of the validity of the two underlying constructs operationalized in the role playing used in class. The study had both theoretical and pedagogical implications in addition to implication with respect to accountability.
