This book has basic contact information for schools and colleges within the trades and technical skills. I’ve looked around. A book like this doesn’t exist anywhere right now, a book that tries to list most of the community colleges and trades-vocational schools in the United States.
I deal with specific profession schools in the next book.
A lot of colleges offer career programs that don’t lead to a degree but rather a certificate for the vocational field.
Local community colleges often offer many programs in the practical skill occupations.
Professional and trade organizations present free or low-cost webinars in addition to their traditional courses available for a fee.
