The Measurable Skill Gain (MSG) Selector from the National Reporting System (NRS) for Adult Education is an interactive decision-making tool to help understand which type of MSG is appropriate for participants in Workplace Literacy (WPL) and Integrated Education and Training (IET) programs, and which types of achievements can count for each MSG type. MSG types 3, 4, and 5 can be used only for WPL and IET program participants.
