NCEA Analysis compares student results from virtual classes (VC) to their face-to-face class results. Each reported learning outcome (ROL) is examined and given a numerical value from 1 to 3, with 1 being the best result. These numbers are totaled and converted to percentages at the end. In 2010, two courses had very poor external exam results with almost all students earning N grades, impacting the overall data even though most students did fine in their regular classes. Two other courses also had weak results that year, while the remaining courses performed strongly.
