Data Pipeline Snapshots - End of Year


The Student End of Year snapshot collects student enrollment information throughout the school year.  This information includes student demographic identifiers, codes indicating the way students enroll and withdrawal from a district, and services students received.  This information is used to calculate dropout, graduation, and completion rates. Additional information about the rates generated by this collection is provided in the rate and report information section below.


The 2020-2021 Student End of Year collection opens on Wednesday, May 12, 2021. 

The EOY collection is broken into three phases. Please see the relevant sections below for more specific instructions for that phase.

Cross LEA process

The Cross LEA process validates if a student previously enrolled in a district have been recovered by another Colorado School district or completed a High School Equivalency Diploma test after exiting the prior district. During this phase most SE700 level warnings are elevated to errors and require district attention. 

EOY Adjustment File - File Layout, Template, Business Rules

The EOY Adjustment file is used to provide additional information about students who were previously enrolled in a district and did not enroll in the current school year. It is typically loaded to address Cross LEA errors, although it can be loaded anytime in the collection.

Adequate Documentation of Transfer

Post Cross LEA SE903 Errors require districts to provide adequate documentation for students who are reported as transferring out of district who were not subsequently reported in another district. More information and templates are provided here.

Rate and Report Information

The End of Year collection provides the data used to calculate graduation, completion, dropout and mobility rates for districts on our Educational Statistics page. This information is published online in January the following year in compliance with state and federal law. Districts have access to advanced reports that provide tentative calculations through the Cognos system in Data Pipeline.
