HISD originally said it wanted to hear from parents by Sept. 25; the new deadline is now Sept. 28. Families can submit their option through the HISD Connect Parent Portal.
Parents that do not respond will be automatically counted as an "in-person" choice in order to facilitate planning, the district said.
Later in the year, parents will again be given the option to change their plans, the district has said.
According to the HISD reopening plan, classrooms will have 6 feet of physical distancing between desks whenever possible, and staggered schedules with in-person and virtual learning may be implemented to manage capacity limits. Student assemblies will be held virtually as well.
HISD plans to resume in-person instruction beginning Oct. 19, with teachers and school staff being asked to physically return to campus Oct. 12.
