A 10-week course called "Communiclearsory" Training was developed to improve the written and oral communications skills of supervisors/foremen in the manufacturing trades. A total of 39 selected supervisors from 2 manufacturing industries in Schuylkill County, Pennsylvania, were assessed by using the Test of Adult Basic Education (TABE) and other assessment instruments. The assessment results were used to develop a curriculum providing instruction and practice in the oral and written workplace communication tasks typically performed by supervisors in their workplace. Two groups of supervisors (39 in all) attended before- or after-shift classes 3 hours each week while receiving their normal salaries. During the course, the supervisors achieved a mean gain of 2.8 grade levels on the language section of the TABE and significant gains in form completion and memo writing assessments; however, they did not demonstrate significant gains in oral communication skills. Management evaluations of the program were positive. (Attached is a curriculum containing the following: course rationale; outline of the course's structure, goals, outcomes, evaluation instruments/methods, and design; and overviews of the instructor and class activities planned for each of the 20 course sessions.)
