Yes — "as" is a Dolch 1st Grade sight word. It follows regular phonics rules, but it's taught for instant, automatic recognition because it appears so often in early reading.
She is as tall as her brother.
"As" is fully regular in spelling and sound, but it's a common comparison word that shows up constantly in early sentences, so it's taught for instant recognition rather than sounded out each time.
