Annual Report: Growth!


Annual Report 2019: Head of School (Elementary • Secondary  Business Manager)

Growth! When I think of this school year, I think of growth—student growth, staff growth, and organizational growth:

  • PreK and kindergarten students made letter-sound connections for reading and writing, deepened their understanding of Jesus’ parables, and solved addition and subtraction problems.
  • Elementary students wrote poems and presented them at a poetry slam, gave team presentations to students and parents at Culture Fair, studied the effects of magnetism, properly formatted Google Docs, played guitar, and used correct stroke order for writing in Japanese.
  • Middle school students did 3D printing, learned about Ryukyu Kingdom history, increased their understanding of Jesus and His ministry, participated in a variety of athletic teams, and connected how temperature, pressure, and density affect weather.
  • High school students analyzed diet plans to determine if they are healthy and sustainable, used spreadsheets to complete research projects in math, studied Biblical principles on stewardship, and developed speeches that take into account occasion, audience, and purpose.


  • Staff participated in book discussions on The New Art and Science of Teaching, Setting the Standard for Projected Based Learning, and How to Differentiate Instruction in Academically Diverse Classrooms; attended training for child safety, MAP testing, mentoring, and social and emotional learning; and interacted with resources from the 17 professional memberships OCSI holds.
  • Organizationally, OCSI upgraded a variety of things, including playground equipment, bus service, food service, and instructional materials for science.


And though OCSI has until 2024 to accomplish the 5 recommendations left by the visiting accreditation team in March 2018, we have already accomplished 3 recommendations by…

  1. Re-evaluating compensation and benefits.
  2. Providing additional support staff to meet the growing needs.
  3. Establishing clear guidelines and deadlines for the completion of curriculum maps.

To learn more about what’s happening at OCSI, check us out on social media (Facebook, Instagram, Twitter) and check out PTF on Facebook.


Thank you for partnering with us as we equip students to walk with Jesus and impact the world for Him. On a personal note, I’m grateful to have been part of the OCSI community over the past 4 years. I will miss being part of OCSI as I head to the US, and I am confident that OCSI will continue to grow.

Annual Report 2019: Elementary (Head of School • Secondary  Business Manager)

Reflection is an important aspect of both a good education and a successful life. It’s important to remember where we started from and the progress we’ve made, and to look forward with goals and hope in mind. Over the past year, OCSI elementary has worked each day to equip students to walk with Jesus and impact the world for him by working toward our expected student outcomes. We’ve made progress as a school, and I know your child has made progress as well.

Reflecting on this year is a great way to celebrate all of the progress we’ve made and helps us make goals for the future:

Understand God, His world, and their place in it:

  • Students learned about God and His world at camp.
  • Students learned about Biblical character traits during Service Week through Athletes in Action and Kids’ Club activities.

Think critically and Biblically:

  • New science curriculum (FOSS) challenged students to think critically.
  • Weekly chapel services encouraged students to grow in their spiritual walk.

Collaborate with others, respecting them as God’s image bearers:

  • Students worked together to share music and drama at the Christmas concerts.
  • After-school clubs taught students new skills in soccer, basketball, crafts, cooking, and literacy.
  • New playground equipment engaged students in play-based learning.

Communicate truthfully and effectively:

  • Elementary report cards are now standards-based to give parents more information.
  • Families celebrated reading during the Week of Reading and Family Reading Night.
  • Older and younger students enjoyed being reading buddies.

Create ideas, products, and solutions:

  • Students created items for the Culture Fair, Author’s Tea, Book Fair, and Kid City.
  • Project-based learning curriculum and classroom furnishings were added in Pre-K.

We’re excited about all of the progress that was made this year and are looking forward to more growth next year! In 2019-2020, OCSI elementary will be implementing social-emotional learning and a new Bible curriculum, and will benefit from increased technology in an upgraded elementary computer lab and with 1:1 chromebooks in grades 4 and 5.

I’m so excited to look back over a year of growth, both inside and outside the classroom. I’m thankful to be a part of OCSI and the amazing people that make it what it is. As we remember that learning is a journey with a constantly moving target, we are focused on growing all aspects of our students as we equip them to walk with Jesus and impact the world for him.


  • During their time at camp, we had several students commit to follow Jesus. We celebrate their decision and commit to walk alongside them as they continue to grow with him.
  • As always, Service Week (see video) provided an opportunity for our students to love of Jesus all over the island and in a variety of settings.
Our students attend our International College Fair in March.

  • Students in chemistry club have been meeting every Friday during their lunch to further explore God’s creation by investigating concepts of chemistry.

One month to go!

PTF Connections:

Greetings from the PTF! One month left till the end of school! It will be a busy time for everyone.

  • On June 7, the PTF will be hosting the Senior Breakfast in the cafeteria. An email went out to the high school parents to support this event. The PTF will be decorating for this event and giving away some special gifts for our seniors.
  • Kindergarten, 5th grade, and 8th grade will be having their promotion ceremonies on June 12. The PTF has prepared a fun gift for these students as well. The PTF will also be helping with the decorations for Yomitan Hall, and a sign up for that will be going out soon.
  • In addition, the PTF will be hosting a end-of-the-school-year party at Toguchi Beach on June 12. We have rented the pavilions from 11:00am – 9:00pm for everyone to enjoy during that time. It will be a picnic style party, so just come whenever it’s convenient for you and enjoy the beach and relax while the kids play after the promotion ceremony and class parties.

This year, there were nine submissions for the PTF Senior Essay Contest from our graduating class of nineteen students. This is an amazing response as it equals almost half the students. So a big thank you to the students for their participation and dedication. On May 30 at the High School Awards Ceremony, the PTF will announce the two winners and give them each a ¥50,000 Amazon gift card for their hard work. All other participants will receive an OCSI towel as a token of appreciation.

Also, a special thank you to those who participated in the potluck during Teacher Appreciation Week. We had an overwhelming amount of food and treats for the staff, and they felt truly blessed by our families.

In addition, in this month alone, the PTF was able to financially support the 5th grade and 8th grade trips, the Junior/Senior Banquet, and the Far East Track and Field Trip, and to donate a significant number of books to both the secondary and elementary libraries. This is all thanks to our parents who support us and devote their time and effort in assisting our fundraising events. We look forward to seeing what next year will bring.
