Summarize this article:

There is no single career path toward becoming a mortgage underwriter, but there are important classes that can help prepare you for a job in that field. It's never too early to start studying mathematics, as you will need to be proficient in math and data analysis to become a successful mortgage underwriter. The best preparation for a career in mortgage underwriting is to take as many accounting and mathematics classes as possible. . Most schools do not offer a specialized degree in mortgage underwriting, but mortgage firms and banks tend to look for certain education credentials in mortgage underwriter applicants. Knowing what courses and degree programs to study can help you secure a better position as a mortgage underwriter.  Loan officers like mortgage underwriters are typically required to earn a four year bachelor degree.  Many mortgage underwriters major in business administration or finance. There is no firm requirement, however, and many successful applicants had other majors but took extensive coursework in accounting, business law, and insurance. . Many banks and banking industry trade groups now offer internships of varying lengths to interested college students and recent graduates. You'll need to actively pursue an internship, and there may be steep competition among other interested students.  Seek out internships by searching online for banking, investment, or credit analyst internships. You can also reach out directly to a banking institution or trade group in your region by searching for them online. The Massachusetts Bankers Association runs a summer-long internship program that immerses college students in the world of financial banking.  Similar opportunities are available for recent graduates. RBS Citizens (part of Citizens Financial Group) offers a year-long training program, which combines classroom studies on finance and credit analysis with rotating positions at the bank to give trainees a comprehensive introduction to all aspects of commercial banking. Once you've earned a four-year bachelor degree, either in business/finance or in another degree with relevant coursework, you're eligible to apply to most mortgage underwriting positions. You'll need extensive on-the-job training, however, before you can become a certified loan officer.
