Children may receive a sub-standard education from non-credentialed, uneducated caregivers.
Children won't learn the things they will need to know in their adult lives.
[16][17]
A child may not learn the same things a regular-schooling peer does, unless an educational professional controls what material is covered.

Because schools provide a ready-made source of peers, unschooling children will have to have other ways to make friends in their age group.
[2][16]
A child's only opportunity to experience people of other cultures and worldviews would be in a religious community, scout group, sports teams, etc. If a child isn't exposed to anything "extra", they might not be exposed to other socio-economic groups.

Fear that a child may be completely unmotivated and never learn anything on their own if raised in a non-manipulated environment.
[19]
A parent may fear they do not have the parenting skills required to guide and advise their children in life skills or help them pursue their interests.
[17][18]
Unschooled children may have to do more legwork before college to gain credentials, such as obtaining a GED.
