When the Kenya National Examinations Council (Knec) released the first-ever Kenya Junior School Education Assessment (KJSEA) last year, many parents were at a loss on how to interpret the results. There were no mean scores ranked from A to E that they had been used to or total marks for placement to senior schools.

Instead, the council reported the results for individual candidates on a 4-level spectrum: ‘Exceeded Expectations (EE), Met Expectations (ME), Approaching Expectations (AE) and Below Expectations (BE)’. Further, each of the four levels of reporting are further broken down into two rungs to form eight-point scoring levels.
