The National Basic foundation Skills Approach uses a status system wherein, proficiency is actually measured on a scale starting from 0 for you to 500 areas. Each rating denotes a place at which you have an 70 per cent prospect of successfully concluding tasks that are associated with a related level of trouble. To aid analysis, these continuous fares are gathered into four skill levels (apart from the problem solving scale, which has only determined four levels), with Levels 1 currently being the lowest tested level of literacy and 5 being the biggest.
