The studies and assessment are based on the Finnish national core curriculum and its objectives. During the studies we are also using the IB Mathematics criteria as one way of ensuring varied assessment methods.
Even the work during the lessons is a part of the assessment. When assessing the lesson work, the teacher follows the Ressu guidelines for assessing working.
The final assessment is based on the curriculum and the level descriptions for grades 9, 8, 7 and 5 given in there. The descriptions can be read in Finnish at https://eperusteet.opintopolku.fi/#/fi/perusopetus/419550/oppiaineet/466344
