How Treehouse choose their teachers and content?

+1

Due to your use of "what they are on about" and "tutor", I'm guessing you are from the UK. I'm not sure how things work in the UK. In the US, a college student would be unlikely to request a professor's CV because the student understands there are hiring standards in place to ensure that a professor is qualified to teach their subject. Depending on the subject, a student can assume that an associate professor has either a graduate degree, a doctoral degree, or an equivalent professional accomplishment in their field. A full-time professor is likely to have demonstrated a higher level of accomplishment. Tenured professors have been selected through a rigorous process during which the quality of their pedagogy and professional work are assessed. This process may take several years and tenure is often denied to competent, professionally accomplished, experienced professors. Furthermore, department websites often feature faculty profiles that provide the same information you would find on a CV. That's not to say that one should accept the authority of a professor just because they are a professor and many college students don't. Hence the popularity of sites such as ratemyprofessor.com.

Whether or not a CV is the best way to demonstrate expertise, I think it is fair to ask about the experience and expertise of the Treehouse teachers. Asking these questions helps to protect oneself from wasting time and money on bad instruction. W3Schools is a perfect example of this trap. As W3Schools demonstrates, the beginner can't always tell from the instruction itself that the instruction is flawed. It takes a third party, such as [W3Fools](www.w3fools.com) to explain that w3Schools isn't a trustworthy authority and why.
