How long do you have to attend college become a Genaral Manager?

There's no single college degree requirement to become a general manager. The necessary education and experience vary wildly depending on the industry. Some general managers have only high school diplomas and extensive on-the-job experience, while others hold advanced degrees (MBA, etc.).

Many general managers in larger companies or those in specialized fields (e.g., hospital administration, finance) may benefit from a bachelor's degree, sometimes even a master's, in a relevant field. However, a degree isn't always a prerequisite. The most important factors are typically experience, leadership skills, and business acumen.
