Oregon Homeschool Science Club
Families come together from all over the Portland Metro area, including Ridgefield, The Dalles, Salem, Oregon City, Seaside, and Hillsboro. No single style of homeschooling guides our families; however, quality instruction and high academic experiences are common goals.
Classes are 90-120 minutes long, meeting Tuesdays from mid-September to the beginning of May, with a long Winter holiday break and a Spring break vacation. Students may take up one course series.
Our program remains a co-op as we strive to keep everyone's costs down. Each classroom has a dedicated parent volunteer for the entire year and a rotating second parent helper. This is not a “drop-off” program; families must stay on the OMSI campus.
You are free to enjoy a cup of coffee, find a quiet corner to read or write your grocery list, or converse with other homeschooling parents.
Events are family activities. Parents and students travel together, explore together, and go home to continue learning.
Courses and trips do fill up early. New events are added throughout the year; watch for email announcements.
Don't hesitate to get in touch with the coordinator to check on availability.
