The online "certifications" are like the "college degrees" you can buy on line..... Totally worthless.
Apply for a job as a gunsmith with one of those, and the employer will simply toss them in the trash.
The better gunsmithing schools are either fully accredited trade schools or junior colleges that offer real degrees.
Here's the available schools in the USA.
The top schools are Colorado Schools of Trades, Trinidad Jr College, and Lassen College.
Get a degree from one of these, and employers sit up and take notice.
