For a private school, you usually still need at least a major in Spanish. Even if you are a native speaker in the language, you can take the CLEP exam and receive credit for the first 2 (beginner and intermediate) years, but you will have to take actually take the remainder of Spanish classes to finish your degree along with the general studies component. depending on many factors, it usually takes 4 years, but some people do finish in 3 or 3.5.

To teach at the junior college/university level, you will need a Master’s in Spanish or at least a graduate degree in another field with 18 hours of Spanish at the graduate level. Universities usually require the Ph.D. in Spanish.

Being fluent in Spanish is great, but it is much easier to obtain the job if you are certified or have teaching experience.
