There are new Levels Reports that give you the skills information by class: all skills, skills attained or skill not attained are your report options. Find these at New Classes>Class Skills/Levels Report.
Please note the information provided about each student in addition to the student name, specific skill and class such as birthdate, skill/subskills and attained date, age, contact phone and last agreement date.
The inclusion of agreement date is especially important because it provides a way for instructors to see right there who may be in the pool or on the gym or studio floor whose parents have not signed waivers.
