So fix the testing facilities requirements.
Easier said than done. Remember that the entire HS maths curriculum in the US is effectively owned by TI calculators, and their lock-in allows them to sell a 1980s-tech 'approved' calculator for ~$100.
Compare this to the $1 scientific calculators you can get in dollar stores (and supermarkets near "back to school" time). These are perfectly adequate, but not "approved". A retired academic friend, ex CalTech, introduced me to these super cheap calculators. He's done a whole suite of accuracy benchmarks on a number of models, and they come out as well as the market leaders.

Absolutely. But do remember at the beginning of lockdown, every school board in the world was competing to buy Chromebooks. Prices and availability were uncertain, and I'm sure mistakes were made.
... I admired the Curta Calculators advertised in Scientific American -- the only hand held digital calculators at that time.
I've held one, once; they are quite wonderful pieces of machinery. Stewart --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
