Welcome to Castillero Middle School

ATTENTION ALL INCOMING 6th GRADERS

The Math diagnostic assessment that was scheduled for Monday April 24th has been cancelled.
This assessment was intended to provide additional data to families about student skills and areas of need.  At this time, Math placement decisions for incoming 6th grade students will continue to be based on the data provided from our Curriculum and Instruction Department. This data includes student performance on unit assessments and SBAC data. At the start of the year all teachers will administer a diagnostic assessment to determine students’ instructional needs.
If you have questions or concerns please contact Crystal Campbell, Assistant Principal of Instruction at (408) 535-6385 ext. 52403 or Darbi O’Connell, Principal at (408)535-6385 ext. 52400.
