This scheme is free to down load on the Astra Zeneca teaching Trust web site. http://www.azteachscience.co.uk/science-teaching/curriculum-materials/special-needs-strata.aspx It covers P levels and L1-4 for MLD pupils. There are assessment sheets and CPD resources. Has anyone used it? What are the good and less bits about it? Do AZ need to update it? any thoughts anyone?
