Dubiski Career High School operates with an eight-period A/B Block Schedule, 8:50 - 4:15. Students attend four class periods daily. 

The only bells at DCHS are at 8:45 am and 8:50 am.  When the time arrives to change classes, students and staff members will simply begin to move. Dubiski has a tardy system, but the expectation is that all DCHS students develop their professional skills and will be responsible with their time.
