LJE HVAC Update and Timeline

Measure K – Las Juntas Heating Ventilation Air Conditioning (HVAC) Update



Every School Day Counts!

The best gift you can give your child is a good education, and the best place to get an education is in school.  It's tempting to extend your vacation or weekend by a few days, but remember those days count as absences.  Just a few missed days here and there, even if they are excused, can add up to too much lost learning time. Absences can affect the whole classroom if the teacher has to slow down learning to help children catch up.  Too many absent students can affect the entire classroom, creating commotion and slowing down instruction.  So please make sure your child is in school every day, and on time.  Our teachers will be teaching and our students will be learning.

CA Physical Education Requirement Accountability

Students in grades 1-5, at all four elementary schools in the Martinez Unified School District, actively engage in the California requirement of 200 minutes of Physical Education every 10 days.  In order to assure compliance with this legal requirement, each site has established “Prep C” protocols for those grade levels that may not reach the 200 minute requirements due to minimum days, teacher prep, and / or assemblies.  These established practices of running laps, dance & movement, and cardio-conditioning outside of the PE class are documented and verified by the site administration on a monthly basis.
