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: Celebrating progress

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.

Our students attend our International College Fair in March.

Another amazing year at OCSI


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

It’s that time again to look back at an amazing year at OCSI! I believe this year has been one of growth both personally and professionally for all. We have taken great strides on pushing OCSI toward even more effectively “equipping students to walk with Jesus and impact the world for Him.”

OCSI operated with 4 divisions, used its Schoolwide Action Plan to refine its program, used a school calendar based on 180 days of instruction, had an enrollment of over 400 and a staff of over 69 full-time equivalents, and maintained its campus through modest capital projects.

The 2017-2018 fiscal year’s audit (completed by Gentetsu Shiroma Licensed Tax Accountant Office) states: “In our opinion, the Financial Statements of the Gakko Hojin Okinawa Christian School properly display the financial position as of March 31, 2018, in all important points in conformity with the Standard of the School Corporation Accounting Principles generally accepted as fair and appropriate in our country as of March, 2018.”


We have made some big decisions this year, including the hiring of a new secondary school principal for next school year. We have acquired new software for admissions, billing, and accounting to simplify our process. Improvements to our gymnasium were also made this year, with more campus improvements planned for this summer.


The elementary program continued to thrive under the watchful eye of Principal Megan Roe and in response to parent feedback, offered six elementary after school clubs included cooking, STEM, crafts/puppets, basketball, soccer, and running. Way to go, Mrs. Roe and the elementary faculty.


It is great to see our secondary students continuing to excel. I have had the pleasure of spending some time with them this year during chapel times. This year saw the computer lab renovated to provide more hands on learning and student collaboration. Thank you, Mrs. Calvin and the secondary faculty. I also want to thank Mrs. Calvin for all of her hard work here at OCSI. OCSI has been made better with her leadership and wisdom. We wish her all the best in what God has for her in the future!


It has been a pleasure for me to serve as the Board Chairman at OCSI, and I am looking forward to what God has planned for our school. On behalf of the board, I am looking forward to next school year!

I’m thankful to be a part of this school community and excited to share all of the growth we made in the elementary program this year. Thank you parents and guardians for all you do to support the school and for partnering with us as we equip students to walk with Jesus and impact the world for Him.

The OCSI elementary program recognizes that students are our future. They are full of potential, are responsible for their learning, and are responsible for using it to serve God and others. This school year has proved to be a time of growth not only for our school, but growth for the individual children in our classrooms as well.  Let’s celebrate their growth!

  • PreK students worked together to problem solve while playing and daily circle times encouraged participation and oral communication.
  • Kindergarten students worked together to explore their world through fun, hands-on activities and are reading on their own through our Daily 5 program.
  • 1st grade students are sharing their original stories and informational writing with peers in order to get feedback and make edits.
  • 2nd grade students have worked hard to develop a community where all students feel valued and can pray for each other and study mentor texts in order to become better readers and writers.
  • 3rd grade students developed their writing and continue to improve their reading comprehension and math fluency.
  • 4th grade students have developed research skills so they can publish informational reports and continue to work on improving their reading and writing skills daily.
  • 5th grade students worked hard in their literature circles, read and wrote biographies, and explored the world of robotics to create their own droid.

OCSI continues toward excellence


Annual Report 2018: Business Manager (Head of School  Elementary  Secondary • Board)

I am glad to report that the 2017-2018 school year was a year in which our school continued to move in the direction of excellence:

  • Support staff displayed great commitment to making OCSI an even better school. Over the course of the school year, they spent countless hours gathering data, planning improvements, and training in new software. I’m grateful to God for placing these faithful people here and for their hard work.
  • We acquired new software for admissions, billing, and accounting. Transitioning to the new software is creating opportunities for us simplify our business office processes. We are excited that it is making it possible for us to serve families better.
  • We began accelerating the renewal of classroom technology, equipment, and fixtures. New iMacs in the computer lab, teachers equipped with convertible chromebooks, old classroom air conditioning units being replaced, and some new student desks and chairs in elementary. More asset renewal and upgrading is expected for the 2018-2019 school year.
  • Several improvements to our gymnasium were completed just before the beginning of the school year. The outside walls of the building were sealed and painted, and exterior LED lighting was installed. More improvements to our campus are currently being planned for this summer.

Thanks to our parents, students, staff, and board members for playing a role in this truly amazing work that God is doing at OCSI.

Students work together


Annual Report 2018: Secondary (Head of School  Elementary  Business Manager  Board)

It has been a great year of seeing the students working together in and outside of the classroom. The Bible reminds us that by joining together we can achieve much. Ecclesiastes 4:9 states, “Two are better than one, because they have a good reward for their labor.” This year the middle and high school students were blessed to be able to work together in a variety of ways.

Service Week

The middle and high school students worked together by serving others through our 4th year of Service Week. They also learned and worked together through hands on learning activities such as science labs and creating websites. The 7th grade English class also created their own Okinawa magazine!  Students have also grown in their leadership skills and worked as a team through participation in sports, National Honor Society, spirit week activities, and the middle school robotics club. OCSI also became approved members of the National Association for College Admission Counseling. We continue to improve our facilities by renovating the secondary computer lab in order to assist with more hands on learning activities and student collaboration.

Screen Shot 2018-05-22 at 5.01.18 PM

This year all middle and high school students as well as teachers also increased their love of learning through reading. Every Thursday afternoon, secondary students Dropped Everything And Read (DEAR) material of their choice for a sustained, silent 25 minutes. The DEAR program supports many positive outcomes—from vocabulary growth, better writing, and understanding of the world, to mental health and the ability to focus, to increased empathy. It has been great to see students and teachers enjoying a good book together.


We will end the school year of celebrating our students by honoring them at the high school graduation on Friday, June 8th at 7:30 pm at the Yomitan Cultural Center and at the the 8th grade graduation on Wednesday, June 13th at 6:00 pm at Sera-en). Thank you to the parents, students, teachers, and staff for a great school year!

I’m excited! I’m excited because this year has been filled with students learning about God and His world, thinking critically and Biblically, collaborating respectfully, communicating effectively and truthfully, and creating ideas and solutions. When students do these things, they get prepared to make a positive impact on God’s world.

Parent Update: May

I’m excited about how students have grown this year! They’ve increased their understanding of God, His world, and their place in it. They’ve developed and demonstrated their thinking, communication, and collaboration skills in a variety of ways, including writing essays, doing science labs, and giving group presentations. And they’ve created artwork, given performances like the Christmas Program and Fine Arts Showcase, and completed service projects.

I’m also excited also about this year’s annual report. You can read about how students, staff, and OCSI as an organization have grown. You can see photos, watch videos, see parent survey results, and more! There are articles by Mr. Jernberg, Mrs. Calvin, Mr. Jerome, Mrs. Kennedy, and me. Check it out!

Finally, I’m excited about being part of a supportive community. Thank you, parents, for supporting your children and OCSI staff. Thank you for being involved in a range of activities, including sports events, Walkathon and Bazaar fundraisers, Field Day, Holiday Market, and more. We invite your continued support through school activities, PTF, prayer, and gifts.
