This study was focused on the development of a textbook in Machine Shorthand for the Bachelor of Science in Office Administration (BSOA) program. Machine Shorthand is a course that trains students to take dictation at a speed beyond the limits of manual shorthand with the use of a stenograph machine.  The study sought to determine the availability of instructional materials (IM) in Machine Shorthand, the accuracy of the IM considering the course objectives as specified in Commission in Higher Education (CMO) 19, series of 2017, and the effectiveness of the available IM in terms of content, presentation, and format. The study utilized the ADDIE (Analysis, Design, Develop, Implement, and Evaluate) model in developing the instructional material. The descriptive development method was used in the study, percentage technique and weighted mean were employed to interpret the results of the study. Using total population sampling, the data were collected from BSOA students of Camarines Sur Polytechnic Colleges (CSPC) who took up Machine Shorthand and BSOA faculty teaching the same course in different schools in the Rinconada area.Results showed that the availability of the IM in Machine Shorthand was assessed as rarely available, however, the available IM was evaluated as accurate considering the course objectives as specified in CMO 19, series of 2017 while the effectiveness of the available IM in terms of content, presentation, and format was considered effective, respectively. Based on the results of the study, a proposed textbook in Machine Shorthand for the Bachelor of Science in Office Administration (BSOA) program was developed to strengthen the knowledge and skills of the BSOA students and enhance their learning capabilities and mastery in the use of the steno machine.
