PEC EPE Agricultural case studies
PEC EPE Agricultural · Put your knowledge to work in context.
The Engineering Practice Examination (EPE) is a professional assessment administered by the Pakistan Engineering Council (PEC), the statutory body whose stated role is "Regulating the Engineering Profession." PEC publishes EPE material through its Continuing Professional Development (CPD) section, including an EPE Guidebook, a policy document for redressal of EPE grievances, and a published result of the 16th EPE (Fall-2020). The examination exists to test the practical, professional competence of engineers rather than academic theory alone, and PEC lists Agricultural Engineering among the disciplines for which it publishes curricula, alongside its other accredited engineering fields. The PEC EPE Agricultural case studies are 5 cases and about 3,387 words.
