Let me give you an example of how poor and pathetic the DOE is. In the US every teacher is required to have the data inform their teaching. Because of that I bought some books on statistical analysis, learned how to use a correlation coefficient and put the data into spreadsheets to help me analyze what was working and what was most effective. But I was required to take ten hours of professional development, so I looked through the offerings and they had one on data analysis. I thought, great, I'll get some pointers from someone who actually majored in statistical analysis. After all I was in NYC, there are 77,000 teachers in NYC, you would think out of all those you would have a certified Math teacher who studied statistical analysis doing this PD. But no, I soon learned that the woman running this PD was completely clueless. I got my first hint when our ice breaking exercise was to stand beneath numbers from 1-10 and she would hit a "random number generator" on the computer. If it got your number you were out. The last one standing wins. So I would simply move to the last number it had picked. They mocked me because they assumed that "random number generators" on computers are actually random, not knowing they are programmed to not give the same number twice. Needless to say the PD was a complete waste of time, she was simply pushing the approach that all principals push, but that the books I had studied had completely debunked.
So that is bad, but it gets much worse. In NYC every regents exam is analyzed and every teacher who is certified to teach that course is graded on the results. Based on that you can identify the four or five most effective teachers in any regents exam over the last three years. Teachers were then graded based on the results with the most effective teachers being graded "highly effective" on their exam results. They do all that already, it is part of the contract. So I naturally assumed they would then use highly effective teachers in a subject to give PD's. Every year we have two professional development days and you can choose where you want to go. And yet, they don't do this. Do you want to know why? It is because PD is used by the DOE to indoctrinate teachers on CRT, DEI, and other useless garbage.
