Should private tutors need to be licensed in order to tutor children?

Sure, I agree with you.

Yes they should, for all the reasons you have given Kathy. In UK at the moment there is heavy emphasis on "safeguarding" both in respect of children and vulnerable adults (I have just finished courses for both). ANYONE having ANY form of responsibility or association with these two particular groups has to have a police background check carried out on them to determine their suitability, CRB/DBS checks (Criminal Record Board). I would definitely support the proposal to license private tutors and would, as part of that licensing, incorporate the checks that I have mentioned. Presumably there will in time be some form of private tutor "watchdog" to ensure standards are maintained.

In my opinion, private tutors must be an experienced teacher not necessarily licensed but have the abilities and background to teach. Many teachers I know are not so good in tutorial jobs, however there are people who can do the job who are not even professional teachers. As long as the tutor or teacher demonstrates knowledge in the subject matter and have the abilities to conduct the lesson effectively and efficiently, and there's a great improvement in your child's learning, study habits and academic performance, then it is not so important if the tutor is licensed or not.

I would definitely support the proposal to license private tutors because they will be completely aware of children 'needs and desires and quite realize how to teach and what to teach rather than any nonspecialist ones

No they should not as a teacher she/he might have the education certificate to be able to teach then no need for another certificate to private tutoring
