Yes! The Logic of English Master Teacher Training Course involves a lot of hands-on activities and practice teaching, so we highly recommend purchasing either the Professional Development Essentials Set or the Professional Development Foundations Set, even if you are not planning to use the curriculum, in order to fully benefit from the training.
While one can still learn a lot about teaching reading and spelling from the training without these items, they are an integral part of the course. Using these materials throughout the training gives the participants the opportunity to work with a fully integrated English language arts program and discover the importance of having all of the subjects aligned and supporting one another. Many key concepts in the training are also taught through the practice teaching activities, so you will not have access to some of the information without the tools needed to complete these sections of the course.
Note: If you already have the curriculum materials, you do not need to purchase a Professional Development Set, as you should have all of the pieces already. We do recommend looking at the Professional Development set for the Logic of English curriculum you are teaching and ordering any individual items you do not already have.
