There are still some states that do not even have contractor licensing in place for home improvements. For some of the states that do have licensing, the license requirements do not include that the applicant demonstrate the ability to do any type of home improvement work. (That is like saying I will issue you a license to cut hair but you don't have to demonstrate that you know how to cut hair......... ouch!) Then why do states bother issuing licenses if there are no requirements to demonstrate competence? Revenue? Or could it be that they need more consumer complaints for Consumer Affairs and BBB to handle? The unfortunate consequences of this problem are that homeowners are the ones who are paying the price by receiving poor workmanship and a cascade of home improvement problems.
Let's be honest, the home improvement industry does not seem to attract the most reliable, honest and competent individuals. The lure of a quick buck and the relative ease to "qualify" to do home improvement work, brings many a "character" to your door. When I was a contractor I needed to hire people for a variety of field positions. Most of the people, who I interviewed and sometimes hired, seemed to have the same type of problems with past employers. These problems consisted of substance abuse issues, honesty issues, and reliability issues. The labor pool never seemed to have an over abundance of talent and employability to pick from.
I remember always reading article after article that dealt with the significant manpower shortage in the home improvement industry. The bottom line of each article would always be the same, "If you can find an honest, reliable and competent person to work for you, pull out all the stops to keep them!!!! Do whatever you need to do to keep that person happy because you'll never know if you will be lucky enough to find someone to take their place." As an owner, it was a very constant and stressful problem to deal with. You were almost afraid to try and increase project production because you knew you would have to try and find someone to do the additional work. Finding employees was always an adventure, an adventure that I never looked forward to.
For the last 10-15 years the number one problem in the home improvement industry is the lack of manpower. Many contractors are training and hiring minorities to try and solve this major problem.
If you were to talk to your state authorities about what is being done to improve regulations and screening in the home improvement industry, they will probably tell you something is in the works or there is no money for more regulations (testing). I have been hearing this for 30 years. The county in which I live (Suffolk County, New York) still does not require any demonstration of home improvement ability to obtain a home improvement license. The fee has consistently gone up but the requirements have pretty much stayed the same. We are one of the highest taxed counties in the country, so I refuse to believe there is no money to develop and implement a better policing and screening process in the home improvement industry.
