In education, a teacher is a person who educates others. A teacher who educates an individual student may also be described as a personal tutor. The role of teacher is often formal and ongoing, carried out by way of occupation or profession at a school or other place of formal education. In many countries, a person wishing to become a teacher at state-funded schools must first obtain professional qualifications or credentials from a university or college. These professional qualifications may include the study of pedagogy, the science of teaching. Teachers may use a lesson plan to facilitate student learning, providing a course of study which covers a standardized curriculum. A teacher's role may vary between cultures. Teachers teach literacy and numeracy, or some of the other school subjects. Other teachers may provide instruction in craftsmanship or vocational training, the Arts, religion or spirituality, civics, community roles, or life skills. In some countries, formal education can take place through home schooling.
Informal learning may be assisted by a teacher occupying a transient or ongoing role, such as a parent or sibling or within a family, or by anyone with knowledge or skills in the wider community setting.
Religious and spiritual teachers, such as gurus, mullahs, rabbis pastors/youth pastors and lamas may teach religious texts such as the Quran, Torah or Bible.

Teaching around the world

There are many similarities and differences among teachers around the world. In almost all countries teachers are educated in a university or college. Governments may require certification by a recognized body before they can teach in a school. In many countries, elementary school education certificate is earned after completion of high school. The high school student follows an education specialty track, obtain the prerequisite "student-teaching" time, and receive a special diploma to begin teaching after graduation.
In the United States, each state determines the requirements for getting a license to teach in public schools. Public school teachers are required to have a bachelor's degree and the majority must be certified by the state in which they teach. Many charter schools do not require that their teachers be certified, provided they meet the standards to be highly qualified as set by No Child Left Behind. Additionally, the requirements for substitute/temporary teachers are generally not as rigorous as those for full-time professionals. The Bureau of Labor Statistics estimates that there are 1.4 million elementary school teachers,674,000 middle school teachers, and 1 million secondary school teachers employed in the U.S

If you feel obtaining teaching degrees online is your best option, then it’s important that you take the necessary time to research all the various online universities and their degree programs. You should think about how many online degree courses that you think will be able to work around your current schedule and whether or not these courses would be transferable to a traditional university or college, if circumstances change in your life and you decide you want to do the degree program full-time.
Make sure the online school that you’re interested in is accredited by the Distance Training and Education Council (DTEC). This will let you know whether or not the degree programs at that school are accepted under the requirements of the state teaching certification. You should also consider interacting with other students and graduates who have completed teaching degrees online in order to find out what their experiences have been like in finding employment.
If you decide to undertake one of the teaching degrees offered at a traditional university or college, you should expect it to take anywhere from four to give years to complete. While this type of setup might be ideal for someone fresh out of high school and just beginning their life as an adult, there are a number of people who are returning to school to complete a teaching degree program. Maybe those returning are unhappy with their current careers or they’d just like the security of a degree to fall back on if times get rough.
