This is the third special issue of "Primary Science," and it is one that offers primary school teachers an insight into an initiative that does wonders for primary science leadership, learning, and teaching -- the Primary Science Quality Mark (PSQM). In this article, Elizabeth Nally shares her PSQM experience and what it has done for her and her school. Nally states that the PSQM experience has been overwhelmingly successful in raising the confidence of subject leaders and teachers, improving whole-school attitudes towards science and, most importantly, increasing interest, curiosity, and enjoyment in children's science learning.
