Some schools offer night classes to allow students to work during the day. After law school you'll be ready for the BIG test. You must graduate from law school before you can take the bar exam and you must pass the bar exam before you get a license to practice in Colorado. The bar exam is given by the Supreme Court Board of Law Examiners. You must pass both of these exams to get your license.
Many people have to take the tests more than once.
While many new lawyers still do that, others will work for local, state, or federal government. As a new lawyer you may go to work as counsel for a corporation or legal service organization, or you may start your own private practice. Some licensed attorneys never actually practice law. They may enter politics, become community leaders and business owners. For every would-be Perry Mason, Marsha Clark or F. Lee Bailey, many more attorneys work behind the scenes.
