Suggested Spelling assessment schedule using the CoSTEY and CoST
Option A | Option B
Two suggested yearly assessment schedules are provided as a guide: Option A and Option B. Schools may select Option A or Option B for a yearly assessment schedule that best suits their unique school context.
In Option A, the CoSTEY component assessments for Year 1 and Year 2 are more spread out than they are in Option B. Also, the Pseudo-word component tests for Years 3 to 6 are more spread out in Option A.
For some school contexts, Option A may be more manageable and appropriate than Option B. For all schools, it is important to implement a consistent assessment schedule each year.
