Taking 5min out of my morning routine to create a throwaway so I can say this is blatantly false. Pre-K does not, in general, decrease educational attainment or increase criminality and high quality Pre-K does quite the opposite.

The Quebec study is an indictment against the poor quality of studied Pre-K provision, that's it.

The quote you pulled from the Vanderbilt study doesn't seem to exist. It's not in the linked paper, which actually states "The effects on the early literacy, language, and math skills of children who attended TN‐VPK were all statistically significant with gains ranging from 37% to 176% greater than those of children not in TN‐VPK." (pg 4).

Interested readers might find this report by the UK Parliamentary Office of Science and Technology useful. Loads of linked studies: https://post.parliament.uk/the-impact-of-early-childhood-edu...

High-quality early childhood education (Pre-K) works really well, especially when combined with positive parent engagement. Rubbish early childhood education often doesn't work, and can lead to worse attainment than no early childhood education, again also dependant on learning at home. A reasonable assumption is that Pre-K/early childhood education is a garbage in, garbage out function - just like parenting.
