PLC Late Start Schedule 2017-18

​​​​​​​​​​​​​​​During the 2017-2018 school year, all four Rockwood high schools will follow a late-start schedule. This schedule supports student learning by providing teachers with time for Professional Learning Communities.

The late-start schedule allows for the following: 

  • Classes will begin at 9:46 a.m. for students on these late-start days. 
  • Sixteen late-start days are included in the school calendar, which provide 90 minutes for teachers during each PLC time. 
  • Bus transportation on will be adjusted on those days to acommodate the late start.

PLCs offer a team approach in education. The focus is on learning rather than on teaching, working c​​ollaboratively, and sharing powerful strategies in the classroom.​​​


Below are answers to some frequently asked questions about PLCs and the late-start schedule.

Q: Why do teachers need PLC time to collaborate?
A: This is the only time teachers of the same course can meet in Professional Learning Communities (PLCs) to provide a common experience for students, regardless of the teacher they are assigned. Teachers discuss what content and skills students need to know for a particular unit. They create common assessments to determine if students have mastered those essential skills. They design interventions to help students who need additional support, and they design enrichment opportunities for students who already have an understanding of certain concepts.

Q: Why can’t teachers collaborate in eight half days?
A: Our current half-day model was put into place years ago for teachers to attend workshops. Educational research tells us the PLC model of focused collaboration impacts student achievement in a powerful way. We have been using half days for PLC time for years. As we increase our expectations for teachers to design common assessments and to discuss results in a timely manner, we have found that teachers need to meet more frequently than once per month to have an effective PLC. The 16 late-start days provide bi-weekly opportunities for collaboration.

Q: Why is the high school different from the elementary and middle schools?
A: It is not possible to organize our high school schedule in a way that provides common planning time for teachers and meets the needs of students at the same time. High school teachers typically teach 2-4 different classes with students of multiple grade levels. We organize our master schedule to maximize the combination of classes that high school students may take.

Q: Did the committee take the needs of families into consideration when designing this schedule?
A: Absolutely. This was a big discussion point. Two parents were at all committee meetings, and all four high school principals got specific feedback from their PTO parents. In fact, it was the parent feedback that resulted in the “late-start” option over early release. Teachers need frequent meeting time, but the time of day isn’t as important. While some families find early release easier, the majority of the parents present at our meeting felt that the late start would be better for high school students, as long as bus transportation would be provided. Our parents felt that there were fewer opportunities for “risky behavior” on late start days vs. early release days. Our parents also felt that it was important to provide the busses at the later time as well to serve working families, in addition to the benefit of students who do not have to spend 90 minutes sitting in the Commons.

Q: Why are late-start days always on Mondays?
A: Late-start days are always on Mondays because it creates a schedule that works better for block classes. It is also advantageous to have late-starts on Mondays due to zero hours. Zero hours are scheduled from Tuesday to Friday mornings in most schools.

Q: Why can’t teachers collaborate outside of school hours?
A: Teacher contracts are based on a 7 ½ hour day. Most teachers fulfill that contract time by working 8 a.m. – 3:30 p.m. However, since they only have 50 minutes per day to plan and grade, teachers end up working far beyond their contracted hours. While our teachers choose to take advantage of many professional learning opportunities after school hours, it is not possible to require teachers to meet before or after school. In addition to the teacher contract, a great number of high school teachers have additional responsibilities outside of school hours. Before school, we have zero-hour classes, AP labs, and student help sessions. After school, we have a variety of activities and sports that keep teachers busy coaching and helping students. It would not be possible to get all teachers of the same course together with the myriad of conflicts that occur before and after school.

Q: I heard that our high school campus will not be open until 9:15 a.m. on late-start days. Why are schools opening at this later time?
A: It is important that all staff members, including school principals and administrators, participate in the collaboration time provided by Professional Learning Communities (PLCs). Ensuring that all members of the high school team can be a part of PLC discussions will improve outcomes of this valuable sharing time among the members of our educational community.

Q: What time will my high school student catch the bus on PLC late-start days?
On PLC late-start days, high schools will be starting 90 minutes later than the normal start time.
The bus schedule for high school students accommodates this change by delaying bus pick-up times by 90 minutes on late start school days. A few things to remember:

  • School buses will stop at the students’ regularly scheduled bus stop location. Buses will follow the same routes on late-start days as they do on regular start days.
  • Students and families can calculate their late-start bus arrival by adding 90 minutes to their current bus pick-up time. For example: if a student is picked up by the school bus at 7:30 a.m. for a regular start school day, this same student would need to be at the bus stop at 9 a.m. to be picked up for the late-start school day.
