The deadline for submitting official Longitudinal Systems Analysis (LSA) data for use in the 2019 and 2020 Annual Homeless Assessment Report (AHAR) to Congress via the Homelessness Data Exchange, Version 2.0 (HDX 2.0) is 11:59 PM PST on Friday, January 15, 2021. In order to meet the final deadline for the LSA submission process, communities must select the ‘Submit for Review’ button on each reporting year. The final round of data quality checks will be run on Saturday, January 16, 2021. Once final data are submitted, your Data Liaison will mark the dataset as ‘Complete.’ For communities that upload a new file and/or notes between January 13-15, the final Errors/Warnings file will be uploaded into the HDX 2.0 by Friday, January 22. Communities will receive an automatic notification once the file is made available. Communities must confirm the final dataset (by selecting ‘Confirmed’ under submission status) within 3 business days of their final Errors/Warnings file being made available. If communities require additional time, please submit a request through the Ask A Question (AAQ) portal by 12 PM (noon) PST on January 15, 2021. You can find full details of the LSA submission process in Section 2 of An Introductory Guide to Submitting LSA Data for the AHAR. Additional resources and guidance are posted to the LSA Tools and Guidance page. Questions?
