# Introduction

![Portland Public Schools](portland-public-schools-logo.svg){width=300px fig-align="center" fig-alt="Portland Public Schools logo"}

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]

# Table

The following table shows math proficiency in 2018-2019 and 2021-2022 for all PPS schools. If you want to see `r top_growth_school`, you can use the search bar to find it.
