# Introduction
This is a report on math proficiency results in [Portland Public Schools (PPS)](https://www.pps.net/). The PPS mission statement is as follows:
> We provide rigorous, high-quality academic learning experiences that are inclusive and joyful. We disrupt racial inequities to create vibrant environments for every student to demonstrate excellence.^[https://www.pps.net/about/portland-public-schools-information/overview]

Can you post the solution? When I include TOC, the quarto document doesn't render at all
Gracielle Higino Coach • June 25, 2026
Hi Eda! Solutions are not posted because they will vary depending on what you decide to do on your document. Do you want to share your YAML so we can try to investigate the issue?
