Attendance The Importance of School Attendance. Research has proven that there is a high correlation between school attendance and academic performance and success, while absence from school is often the greatest single cause of poor performance and achievement. Beginning on September 2016 Essex Center For Technology (CTE) introduces a new Online Student Absence Reporting. To report your student’s absence, please fill out the absence form. You will receive a confirmation email back after information is submitted. Good communication is a key.
