Each year, my school provides each teacher with $100 of “professional development” money. I don’t know exactly why they call it that (hence the quotation marks). For things like conferences, online courses, etc., we have a really great fund to tap into. No one I have talked to has ever been denied money from that fund. This $100 is more of a mystery. You have to submit receipts for it, and it needs to be for things relating to school. I could buy school supplies, for example. Professional development? Tenuous.
And, in fact, each year there’s a book fair with tons of books for students and teachers to buy from. It’s a fundraiser for yet another something or the other. I learned that it’s tradition for teachers to never use their money during the year, and during this week in May, pick out $100 worth of books from the fair to count as their “professional development” money. This practice is so institutionalized that you don’t ever have to take out your wallet to get the books; the people running the book fair just write your name down and the total amount you’ve spent on a piece of paper and you’re done.
Streamlined, and sweet. Just the way I like it. 
I’m not complaining. How could I complain about this? But I do wonder why this money needs to be couched in terms of “professional development”? (No matter how broadly you look at it, my Martha Stewart books will never be professional development.) My suggestion: why not just call it a “we like you teachers and we want to give you a little pick me up” perk and be done with it? I like my school. But for some reason, getting a $100 and being it’s told because “we like you teachers and we want to give you a little pick me up” is just so much more satisfying than “professional development.” So I’ll pretend that’s what it’s explicitly earmarked as and go along merrily.
 I know you’re wondering… I bought two very smart-looking hardcover Martha Stewart books (“classic” and “new” recipes), Middlesex (Jeffrey Eugenides), and The Secret History (Donna Tartt). I’ve read the Donna Tartt book before. One of the best books I’ve ever read, hands down.
Return the Tartt book; I have your copy (you loaned it to me years ago).
