CTL recommends the following in terms of scheduling:

Mathematics classes meet every day for a minimum of 40 minutes and science classes meet for a minimum of 40 minutes for four days each week and once a week for a minimum of 60 minutes, to provide time for experiments.

Professional Learning Communities are enabled by providing a class period, at least one day each week, for teachers to collaborate.

Classes are heterogeneous to the extent practical, and tracking is minimized.

After-school tutoring sessions are established to enable heterogeneous classes to be successful by providing struggling students a chance to learn from their teachers and/or peers outside of the normal class time, and to take retakes.

Embedded professional development is in place to enable teachers to learn both content and methods from each other while creating a more open-classroom environment.  For instance, scheduling could maximize the opportunities for teachers to observe each other.  This help teachers of the same course learn from each other while teachers can also learn how to teach new courses from one another.
