The material „Reflections on self-assessment at children aged 6-7, from the point of view of assessment without grades in primary education” outlines a view on self-assessment issues in general and, in particular, at pre-school age. There is revealed the specificity of pre-school self-assessment and its formative advantages, the connection between consciousness, self-image and reflexive actions. Several dimensions of self-assessment at pre-school age are examined from the point of view of linking to the process of critical assessment through descriptors at the primary education stage.
