eLearning That Empowers You

PTRA Academy: A web-based learning opportunity

Taking time out of busy schedules can be challenging. PTRA Academy provides all the great benefits of relevant, easy-to-use online courses that are accessible any time and any place; just log in and start learning! The courses are self-paced, self-guided, and interactive with visually engaging graphics. Concepts can be immediately applied in examples and assessments, and every course completed will be added to a transcript, with printable completion certificates.

The list of subjects is extensive, and more will be added every quarter. These cost-effective courses are formatted in either of two ways: Fundamental or Lightning Learning™ (LL). The Fundamental courses offer in-depth information on an array of related components within one manufacturing concept, while the Lightning Learning™ courses tackle one focused concept in a short, fast, and comprehensive manner. Both are available upon sign up for 6 weeks at $100 each for any Fundamental course listed and $50 each for any Lightning Learning™ course offered – available to PTRA members ONLY!

This is a great opportunity to improve skills, bottom line, and career prospects.
