Pros
Bonding with students, teachers are usually down-to-earth, freedom to make scheduling, freedom to basically sit around and do nothing, the feeling of superiority that you're a 'teacher' (when, in reality, you're nothing more than a glorified babysitter for wealthy, lazy and apathetic parents who care none whatsoever about their kids' education).
Cons
Basically everything. Technologically based school...with consistent book and internet problems. Freshly graduated, dedicated novice teachers...forced into teaching subjects they have never even took themselves before. An administration...of which is under-qualified (the director at my campus was/is a joke) or overworked (aforementioned director too lazy to do own job, so she created bureaucratic system to hand off her work to other employees). A pay rate...that requires teachers to work other jobs in order to make ends meet in Orange County (while the students are too wealthy too function, paying nearly $20,000 a year for a job in which the average teacher makes $20-$21 an hour). A 'one-to-one' setting...where students meet only once a week for 50 minutes to learn a subject that they forget five seconds later because homework is too easy, they're rich and have all the excuses in the world, and they have no consequences or accountability in their life. But overall, the concept of the school is so convoluted in presenting itself as alternative and advanced, that its 'function' as an education system is overshadowed by the reality: a for-profit company, that will sell watered-down versions of classes to lazy rich kids with 'learning differences.' I taught 11th/12th grade courses (e.g. 'Physics' on transcript) at a 7th/8th grade level (e.g. content basically middle school science) because the students are not able to handle the true material and their parents (in the true Orange County mindset) think they can just spend money to get grades. I think it's important to note here a famous slogan among kids at the school is "Pay for A's." Halstrom is a disservice to education. I am ashamed to say I worked there. If you believe you can weather all of the above cons for a paycheck (which, as previously stated, is abominable considering the line of work and the rate they charge the kids), then best of luck to you. Otherwise, I recommend not spending your postgrad becoming jaded and hating the education world.
