My code works in the workspaces console; However, I am getting an error in the challenge task window:

See subject line.

teachers.py 
def most_classes(edict):
    most = 0
    teach = ''

    for item in edict:
        num = len(edict[item])
        if num >= most:
            most = num
            teach = item
    return teach

def num_teachers(edict):
    count = 0
    for item in edict:
        count +=1
    return count

def stats(edict):
    elist = []
    for item in edict:
        elist.append([item, len(edict[item])])

The only thing that you're missing is the return on stats. The other thing in my code is that I'm using the dict.items method and I used the dict.keys method.

def most_classes(teachers):
    final_teacher = None
    class_count = 0
    for teacher, classes in teachers.items():
        if len(classes) > class_count:
            final_teacher, class_count = teacher, len(classes)
    return final_teacher

def num_teachers(teachers):
    return len(teachers.keys())  # This is a better way of doing it.

def stats(teachers):
    courses = []
    for teacher, classes in teachers.items():
        courses.append([teacher, len(classes)])
    return courses  # The only thing that I can see that you're missing
