How did OCSI grow during the past school year?

OCSI Connections:

I’m excited that as an organization, OCSI grew this year. Ways that come to mind include:

  1. Elementary offered six after school clubs (cooking, STEM, crafts/puppets, basketball, soccer, and running).
  2. Secondary students participated in the drop-everything-and-read program.
  3. We renewed 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.
  4. Students, parents/guardians, and staff worked together on the accreditation process.
  5. OCSI increased the number of professional memberships, including the Child Safety and Protection Network.
  6. We improved our curriculum so it is further in line with best practice and research.
  7. Elementary purchased instructional materials for science.
  8. We implemented MAP testing for grades 3-8.
  9. We made improvements to our gym—the outside walls of the building were sealed and painted, and exterior LED lighting was installed.
  10. We refined our Schoolwide Action Plan, based on recommendations from the visiting accreditation team.

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!

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

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.

  • We continue to develop and improve our curriculum so it is in line with best practice and research, including new Daily 5 classroom libraries, a Writer’s Workshop program, new social studies resources, and a robotics unit in 5th grade.  
  • Through partnership with the Parent Teacher Fellowship (PTF) we’ve been able to provide parent Bible studies, cooking classes, a Culture Fair luncheon, Week of Reading, and provide new recess toys for the students.
  • In response to parent feedback, we were excited to be able to offer six elementary after school clubs this year- cooking, STEM, crafts/puppets, basketball, soccer, and running.
  • Elementary and Kindergarten Christmas programs highlighted the talents and energy of even our youngest students.

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!

This year has been filled with learning!


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

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.

At OCSI, we’re excited to see…

  • PreK – kindergarteners identifying what part of a story doesn’t belong, working together to figure out how to reinforce bridges on train tracks with blocks, and reading to a partner during Daily 5.
  • Students in grades 1-2 understanding the importance of praying for others to create community, exploring the concept of symmetry through portrait drawing, and getting feedback from a partner before editing.
  • Students in grades 3-5 using decimals to the thousandths place, thinking about people and places that are important to them in order to write small moment narratives, working in groups on posters, and designing their own inventions on paper.
