Pros
Loyal, competent, and dedicated teachers. Curriculum encourages and teaches independence, self-reliance, and public speaking. Benefits? Your first child's tuition is covered. (But you still have to order uniforms through Challenger's suggested supplier, which of course, is owned by a relative of the owner. )
Cons
Corporate management. Mid-managers (headmasters and directors) have little or no loyalty for teachers and/or their hands are tied because they're in fear of speaking up about grievances and losing their jobs. Challenger has a take-it-or-leave-it approach to employment and customers. It's appalling to see a company where management is so indifferent to their customers' needs and cannot offer any flexibility or empathy. Politics has firmly advanced into the classroom and teacher training. It's so blatant and perverse that teachers now shake their heads and accept it as normal company practices. The real victims here are the children, whose lives are interrupted when families debate whether to re-enroll or look elsewhere.
