The circular dated October 18, 2022 is regarding the Formation of Hubs of Learning- for Collaboration among Affiliated Schools for self-improvement. A number of orientation programmes for Hub leaders (Lead Collaborators) as well as members were conducted in May to July 2019 and again in January, 2020 for successful implementation of the programme. However, during Covid – 19 pandemic time, the functioning of HOL was largely impacted by epidemic. But, the HOL has been restructured and a dedicated HOL portal has been created with multiple functionality, the Hubs of Learning as well as the individual schools must keep records and upload it on the HOL portal its case studies, e-content, teacher manuals, documentation of innovations and best practices, etc. which may subsequently be disseminated by the Board as exemplars for the teaching community for wider adoption/adaptation/replication. Link for more details is given in the document.
