Note: This story has been updated to reflect a revised school calendar provided to WHAV. Haverhill students will be returning to their classrooms beginning in April. The Haverhill School Committee last Thursday approved a plan submitted by Superintendent Margaret Marotta to phase-in full-time, back-to-classroom learning beginning Monday, April 5. Marotta said the schedule was based on the recommendation of state Education Commissioner Jeffrey Riley. Specifically, Haverhill’s phase-in will have all kindergarten and grade one students in the classroom beginning April 5, while all cohort A students in grades 2-12 will attend in person on April 5 and 6. All students will attend remotely on April 7. On April 8 and 9, all students kindergarten through grade four will attend in person along with cohort B students grades 5-12.
