District News & Events




On Tuesday, Sept. 13, the Twin Rivers school board met during regular session at the District Office on McClellan Park.


Please click HERE for meeting highlights.



In our efforts to keep parents informed, we wanted to let you know that students in grades 7-8 will be using supplemental instructional materials through the News ELA (English Language Arts) program.


The News ELA program provides teachers with access to current event articles like those found in state and national newspapers.


The goal is to bring relevance to core curriculum and to provide students with access to a large quantity of material that matches their reading level and interest levels. Teachers are able to adjust the complexity of the text for struggling readers.


Please contact your principal if you have questions about the News ELA program and/or it resources.
