Generally, training is your own responsibility.
There are many training sites online. I use Pro-solutions, myself.
Child care is not like most professions with starting requirements unless you are opening your own. Many do require your obtaining a CDA, degree or TCC before the end of your first two years. It is also generally expected you do that on your own time and money.
Most child care workers are unappreciated and underpaid. It is sort of the expectation for our profession.
Notice how they protected public school teachers by sending them home paid while asking us to take extra children, work longer hours and give parents discounts during COVID-19?
It really is just the field, entirely.
