I would like to know what the teachers who have used this service thought of the quality of substitutes provided by the company. Teachers do not like letting just anyone into their classrooms, or they shouldn't if they care about their students. There needs to be reviews by teachers who have used this service. What does a company hundreds of miles away know about a particular school or a particular teacher that makes it the best judge of who goes into a classroom? The reviews that are available for Source4teachers only review this company as an employer. As a future client, I want to know how it really is as a service provider.
