A district should use the CIP number 15.15000000 and state name: Engineering Related - PLTW. This CIP number should contain only the PLTW courses. Any school that agrees to implement PLTW is agreeing to implement a minimum of four PLTW courses. Each course is one unit in length; therefore, the PLTW program will contain a minimum of 4 units of instruction. No additional courses should be included in the Program using the CIP number 15.15000000. Schools may find it appropriate to incorporate PLTW courses into other CTE programs. For example: Digital Electronics may be a course within an automotive technology program or Introduction to Engineering may be a course within the Manufacturing technology program. Although core courses are important for students within PLTW, core courses, such as Math and Sciences, should not be listed within the PLTW program.
