The Cambridge Street Upper School Parent Caregiver Organization (Cambridge Street PCO) is a 501c(3) public charity that supports the work of the teachers, staff and caregivers of the Cambridge Street Upper School (CSUS) in Cambridge, MA.

Our goal is to raise funds to support and supplement the great work being done at Cambridge Street Upper School.


CSUS serves student scholars in grades 6, 7, and 8 with a total student population of approximately 250 youth ages 11 to 14. The student population is wonderfully diverse and culturally rich. Of the scholars attending CSUS 22% live in a household where the first language spoken at home is not English.

The school is fortunate to be the host of the middle school Autism Spectrum Disorder program of the Cambridge Public Schools and in part those scholars help make up the 25% of students with disabilities. The greatest challenge to those working with and supporting these scholars is that over 50% of the children have high needs as defined by the MA Dept. of Education and over 35% percent of the young people attending Cambridge Street Upper School live in economically disadvantaged households.



A big thank you to everybody who helped to make this event a big success. Come back next year!
