Educational requirements are typically a Bachelor's or Master’s degree in early childhood Education. There may be problems such as culture immersion, foundations of Education, and school and community regulations. To teach at a public school a teaching credential/ state license is required to teach Elementary and Early Childhood instruction techniques. Many programs also require a supervised student teaching internship. Some states also require that master’s degree in elementary education after receiving their teaching certification. A First Grade teacher may work in a public, private, or charter school. Charter schools are independent public schools with rigorous curriculum programs and unique educational approaches. In exchange for operational freedom and flexibility, charter schools are subject to higher levels of accountability than traditional public schools. Charter schools, which are tuition-free and open to all students, offer quality and choice in the public education system”(California). Communicating with children and encouraging academic achievement is an essential part of the job, along with patience. Teachers communicate with supervisors and parents about the behavior and the Educational level of a student. In addition to grading papers, teachers write out report cards with specific feedback describing each child's performance, and have a one-on-one conference if needed and/or wanted. Common job duties are leading group study by demonstration and discussion, introduction of new concepts, behavior and rule enforcement, objective communication, evaluation and observance of students, challenging students in preparation for advanced Education, and material preparation and delivery.
