Two things have made me think about this.
One was the recent thread on Venezuela Fury, Tyson's daughter. Her situation appears slightly different as apparently she did receive tuition online but it made me look into the wider situation.
I know there has been improvement, and that many Roma & travellers families don't do this. But it shouldn't be allowed in the first place. Yes, some who do may homeschool their kids properly, but how many?
There needs to be more regulation of homeschooling.
Why do Roma & traveller kids often slip through the net? Is it sometimes linked to families moving around so children move from one LA to another?
There' nothing wrong with kids preferring to pursue technical options than academic, or living the travelling lifestyle. But school would give them a chance to choose.
