Register for CutTime

CutTime is a management solutions platform that enables the Harrison Orchestra Boosters (HOB) to communicate with our orchestra families. As orchestra is a co-curricular class, the Harrison Orchestra Boosters provide additional support for the program throughout the year by providing enrichment to the orchestra curriculum. In order for the HOB to communicate with our orchestra families, we will be utilizing CutTime for communication, inventory and music management. In addition, CutTime will also serve as a back-up for us in case CTLS goes down for any reason. (For those families who were familiar with “Charms” from previous years, we have replaced Charms with CutTime).

Remote Learning for Fall 2020 – CTLS

Welcome to the 2020-2021 School Year!

All remote learning will take place in the newly developed CTLS (Cobb Teaching and Learning Systems) learning management system. This platform will be the main system in which we interact and have class as directed by the Cobb County School District. We will update our plans of operation as guidance and updates are given by the Cobb County School District‘s Learning Everywhere Plans. 

CTLS Learn
Students will access the CTLS Learn website to login into class each day and will be able to find what we are doing in orchestra class along with all of their other classes at Harrison on this platform.
If a student misses class, they can get what they missed from CTLS under the digital session titled “Week # – Click Here for Class”. It will give an outline the material from the day.

CTLS Parent
Parents will access the CTLS Parent website to login and see announcements and communication about orchestra class as well as information regarding other classes and school information at Harrison.
