This report (8 page PDF) offers a set of principles intended to inform the practice of assessment in the upcoming pandemic-complicated school year. Many of these recommendations would be suitable in any year, for example, 'do no harm' and 'engage parents as parters' (to which I always want to add, 'where possible', since parental engagement cannot be taken for granted for many students). Others would make good policy, like " Don’t use assessments for accountability unless they were designed and validated for that purpose." And finally, there is good advice about focusing on student's physical and emotional well-being. Overall, I think, the message is that assessment in this coming year will be secondary to other priorities. Maybe it should always be secondary. See also The Evidence Project.
