Simply put, upskilling helps you move up, while reskilling helps you move on.  Upskilling is training to augment existing skills, while reskilling is training to learn new skills.  Upskilling with advanced and enhanced knowledge and skills helps you succeed in your current career, while reskilling with new knowledge and skills helps you perform a new job. 

Credentialing on Soft Technical Skills from www.Lesson-Up.net provides either reskilling or upskilling, depending on the trainee’s goal at the moment.
