Require schools to allow children the option to retake their year next year

Assuming that the lockdown continues into Summer, it will have cost pupils ~half of their total time in their present year.
Mostly, this will have little impact, but we worry that it will adversely affect the social/intellectual lives of:

Reception children just learning to read or add
Those just integrating into new high schools or colleges
Those preparing for the 11+

The cost of reducing workforce entry rate for a year is far less than that of hindering the education of a whole generation.
