Frequently Asked Questions

General

Q. Which schools need to submit data for this collection?

A. Districts, BOCES operating schools, and the Charter School Institute will need to submit data for all public schools (school system code 1) serving grades kindergarten through 12th grade (006-120).

Q. Which schools do not need to submit data for this collection?

1. Public schools only serving pre-k (004) do not need to submit data. If your school serves grades pre-k and above, pre-k may be omitted from the data submitted for the rest of the school.
2. 100% Home Options Schools (school system code 10) do not need to submit data.

Q. Do I need to include summer school calendars in this collection? 

A. Summer school calendars should not be included in the Instructional Days and Hours collection. 

Hours of Instruction

Q. How do I classify assemblies?

A. All planned assembly time should be counted as instructional. 

Q. How is graduation day calculated?

A. Graduation day (in which no classes or tests are held for any grade) cannot be included as an instructional day or hours. If other grades continue to have instruction and/or testing, these grades would be expected to have a higher instructional hour count than seniors.

Q. How do I classify remote learning days?

A.  The use of remote learning days can only be used as instructional days and hours in the event of an emergency school closure, meaning there are no planned remote learning days allowed. Since this collection asks for information based on your planned academic calendar, remote learning days should not be factored in.

Passing/Recess Instructional Indicator

Q. How do I know if passing and recess are counted as instructional time or non-instructional?

A. Each district school board should have a policy on whether or not passing and recess are counted as instructional time. You will need to locate and review your district's policy on instructional time to determine if passing or recess are counted as instructional time. If a policy is not defined, assume that passing time is counted as instructional time and enter a 1 (yes) in this field.

Total Teacher Workdays

Q. Our new teachers attend an orientation the week before the rest of our teachers return. Should those additional orientation days be included in the Total Teacher Workdays?

A. Total Teacher Workdays is teacher contract days and should not should not include orientation days for new staff. To calculate, use full-time, full school year average of teacher contract days.
