Yes, really. It is not only required in schools, it is the only way children learn writing. And it is the only way ~90% of adults use for daily purposes (90% is just my guess, of course).
Moreover, when we learned English at school (4th - 10th grades, I had English as a foreign language class), we used the same cursive style to write English letters. And we did not know they are not frequently used.
Yes, I am aware of the fact cursive writing has become uncommon at least in the US (I am not sure about the UK though). But believe me, when I learned first time about that fact (that you do not use cursive), I was as surprised as you are now

'Cause it would take for me ca. twice longer to write in block letters as compared to the cursive, where all the letters are joined into a single line within a word boundaries.
