Analytical Chemists require a bachelor's degree in chemistry, physics, or other related field just to obtain entry-level positions. Obtaining extensive lab experience through work-study programs or internships is highly recommended.
Individual law enforcement agencies employing forensic chemists may have varying educational requirements and other qualifications. The U.S. Drug Enforcement Administration, for example, requires forensic chemists to have at least 30 semester hours in chemistry, six semester in physics and courses in calculus.
