We are grateful to our families for being valued partners as we work together to educate students in Highline. One of our priorities is to support students in developing life skills. Over the next several weeks, students in grades 3-12 will be asked to reflect on their own skills.

COVID-Relief Dollars Put to Work

Did you hear…the federal government distributed millions of dollars to schools to address COVID-related expenses. These are one-time funds to help schools through the challenges of the pandemic. One way we are using these funds is to improve air quality in all of our schools and to purchase cleaning supplies and personal protective equipment (PPE).
