(The hypothesis of this,) The chief reason why native speakers of English fail as teachers in their duties, consists in their lack of knowledge about the teaching culture in which they work. (different countries!)

There seem to be three essential components that contribute to the success of teachers in teaching english.
Language, Techniques and Culture.
As it follows from the teachers' and learners' interviews, the missing link on the chain of success is the "culture", meaning teaching culture or socially expected classroom experience. Native speaking teachers of English often demonstrate teaching techniques, which seem interesting and are treated with enthusiastic welcome. The chief reason of it, however is the novelty of these practices and teachers/learners expectations of a miraculous result, supposedly achieved with the help of these techniques. When with the time, however, the audience feels that the chosen way of instruction does not meet their expectations of how language should be taught, muffled objections can be raised and subdued requests can be voiced about the change of tactics. This change is not likely to happen in most cases for the simple reason of the teacher being unaware of what has actually gone wrong. Another possibility is that the teacher may not be aware of the critique and lack sufficient feedback from the classroom.

How Native English Speakers Can Be Better English Teachers

Native speaking English language teachers are very much needed in almost all the world in most cases they are met with traditional hospitality, behind this generally welcoming attitude there may often be a certain critique. One of the chief values of native English language speakers as teachers lies in their command of English and demonstration of their teaching techniques as a glimpse of "foreign" teaching methodology. In some instances, due to cultural differences and differences in expectations, these teachers are not as effective as they could be.

A person could be raised in a non-English speaking country by native-English speaking parents and that would, in my opinion, also make them a native speaker.

Tip; Define native speaker of english, Someone that has been speaking English since the day they were born? Or someone who came from a race that orginally spoke English.

Ok i put that in the message to you i see you missed that part so here it is again, Classes have for instance 30-50 students in them. you may have to write progress reports on students plus lesson plans in some cases.

here's a little something:
You cannot get consecutive contracts with westgate.
Depending on your performance, salary may be increased after the completion of each term in the Westgate Program
Here is some more info:
1. There is a 2 month interval between Westgate contracts. You are not paid during this time and you can not live in Westgate accomodation during the interval. that is what is meant by 'non-consecutive. You can teach more than one but you don't get paid in the interim.
2. Westgate is an outsourcing company in which you work for a proivate company on university campuses. You are teaching university students but it is not like teaching university classes. Classes have for instance 30-50 students in them. you may have to write progress reports on students- the more flowery and positive the better for your own evaluations.
3. my only advice (without being the prophet of doom here) is to get a Masters degree, start working part time at a university (not through a dispatch like Westgate, unless you happen to meet some university teachers) and then start networking and building up your resume. Get experience teaching as much as you can.

English is so widely spoken, has often been referred to as a world language use in most countries for informative communication between peoples of different countries, although English is not an official language in most countries, it is currently the language most often taught as a second language around the world. Some linguists believe that it is no longer the exclusive cultural sign of "native English speakers", but is rather a language that is absorbing aspects of cultures worldwide as it continues to grow and English teachers are in high demand around the world.

Tip:
Significant results: Nearly 84% of the responding school stated that a job seeker's portfolio can be a significant selection tool along with references, credentials, transcripts, résumé, cover letter, and personal interview. A well-prepared portfolio can contribute to your success. However, hiring officials caution that a poorly-constructed portfolio can diminish your chance of future employment in the teaching field.

Portfolios that reflect standards and recognized teaching proficiencies can increase job chances with a TESOL diploma or TESOL specialization courses

Tutoring and teaching children and/or adults you will find are the most required. also business certification would be advisable as will . TESOL Certification is a great plus, but there are many teaching opportunities in all disciplines the question is what do you want to specialize in, in reality it is you decision, happy learning lol
