Exciting personal news! After a few revisions, my first 'sole-authored' paper just got accepted for journal publication! 🎉 You hear such hair-raising experiences of some authors with their reviewers, so I'm so grateful for the 2 incredibly helpful anonymous reviewers involved 😌
Some exciting news 😌 Thrilled to share my 1st journal publication, published in Development Southern Africa. I show that ⬇️ class sizes are only associated with ⬆️ learner outcomes in *wealthier* public high schools in SA. Why? Thread below!
Full paper:
So very happy to hear that the R350 SRD grant has been extended, and expanded so unemployed CSG caregivers are now eligible. Will likely improve the grant's unequal gender distribution (~35% of recipients = women). So many fantastic researchers have contributed to this outcome!
To support those who have no means of supporting themselves, we are reinstating the Social Relief of Distress Grant to provide a monthly payment of R350 until the end of March 2022.
This has been made possible by the slight improvement we have seen in our revenue collection.
Grateful for the opportunity on

Hi Nick. Just in case you’re not aware, the QES stats you’re referencing exclude the agricultural industry and entire informal sector, so this tweet may be a bit misleading.
Refer to the QLFS for total employment estimates, the latest of which (2023Q1) = 16.2mil 👍
