Introducing InterSIS - the International School Information System re-imagined

After six years of continuous development, we have re-imagined the school information system and we are proud to announce the first integrated school management suite: ManageBac for planning, assessment & reporting, OpenApply for admissions & enrollment and InterSIS for international school information management.

ManageBac, OpenApply and InterSIS in concert provide the first integrated school management system built from the ground up to support international schools with curriculum planning, assessment & reporting, attendance & behavior, parent access and a state-of-the-art billing & finance solution built on top of Xero - the world's leading cloud accounting solution.

The Beginning

When we first set out to build ManageBac six years ago, we were approached by the English Schools Foundation in Hong Kong to participate in a tender for the Teacher's Gateway, which was a system widely used from 2008 onwards by all ESF teachers, students and parents.

The ESF Teacher's Gateway provided us with great insight into the common features that every IB school required, and while we lost the tender to a local competitor eClass, over the following five years, we built-out many of those functions into ManageBac in a sustainable way based on the collective feedback of hundreds of IB coordinators & teachers.

The key difference in our approach was that we standardized functions, so that they could be used globally across all IB schools, rather than blindly customizing for individual schools and saying "Yes" to every request, which would have rendered many of the same functions useless.

The ESF tender was our first exposure to the hodgepodge of information systems, integration challenges, and a complex committee-based decision-making process.

What were some of these core systems common across many IB schools?

In the ideal world, there would be one account for every student, parent and teacher with a centralized identity (e.g. if the home address was changed in one system, it would be reflected across all systems), but the issues were much deeper than just having information synchronized.

These were our observations:

  • Every new system was an additional silo requiring teachers & students to learn a new user interface.
  • New systems necessitated professional development, particularly for less tech-savvy teachers, who had just become comfortable with the old system and saw no reason to switch.
  • Additional systems required IT maintenance & support, requiring the IT department to familiarize themselves within each new system and to provide training & account provisioning support to students, parents and teachers.
  • Fragmentation resulted in greater inconsistency of information across each school's systems without respecting the single-source-of-truth principle.
  • Many systems were locally-hosted resulting in higher maintenance costs, increased a need for continuous monitoring and day-to-day management in applying patches or upgrades.
  • Schools were left with little alternative, but to try to patchwork together and integrate the systems in whichever way they could amongst providers, which frequently did not step back and cooperate in a rational way.

The result of this is that even after six years of working towards this goal, schools have no single integrated school management system that works seamlessly out-of-the-box.

Market Failure

Why weren't these issues addressed over the past 7 years?

These were the reasons from our perspective looking externally at the situation:

  1. Lack of sufficient scale to support the service and absence of stable management.
  2. Conflicting demands and lack of product focus: the international school segment accounted for a minority, 5-15% of each systems provider' overall business. It was not a critical priority.
  3. Failing to adequately reinvest in product development with dated user interfaces from the 1990s.
  4. Promising improvements without delivering anything consistently.
  5. Commitment to the client/server model, which was both difficult to maintain and support, and which resulted in every school having different versions of the same system.
  6. Lack of transparent pricing by vendors made the process highly confusing for schools to navigate without any basis of comparison.
  7. Pushing for extreme customization in an unrealistic timeframe, rather than collaboratively working to build a shared product benefiting all schools.
  8. Extreme risk aversion among IT & Technology Directors to undergo a systems change in the absence of a reliable and trustworthy technology partner (i.e. this would mean serious career risk)

The result of this was that in the span of the past six years, we have seen several major companies go into a run-off scenario (i.e. customer churn of 10%+), where product improvements were not made, where a new owner fails to rectify the issues, where price increases are unreasonable and unwarranted, and schools are left with an unreliable partner with deteriorating support.

Why transition to the cloud?

Moving your school information system to the Cloud provides greater accessibility from both school and home, lower total cost of ownership, and greater reliability, redundancy & safety with automated backups and 24/7 monitoring.

InterSIS can be hosted on our secure cloud at iWeb Montreal data center, or you can deploy InterSIS directly onto your Amazon Web Services account in any global data center with full control over your data and peace-of-mind.

Data Protection & Security

We take data protection seriously. If you are hosted on our cloud, your data is written to multiple disks on RAID storage instantly and backed up daily across multiple locations. Daily incremental file backups are performed via an encrypted SSH connection. Version history enables us to go back in time to retrieve backups at a specific point. Weekly disk image backups are stored securely with encryption on Amazon EC2 servers in Singapore. We maintain three weeks of disk image snapshots.

Complimentary Cloud Backup

If you are using any of the following student information (or management information) systems (SIS/MIS), we can provide a complimentary, no cost backup & migration of your core student & family data, so that you can test-drive InterSIS first hand and see how it functions with OpenApply & ManageBac.

  • Advanced Learning Facility (formerly Serco)
  • Rediker AdminPlus
  • WCBS
  • Powerschool
  • Capita SIMS

Migration, data cleansing and export typically take between 1-2 weeks and are done through our partner Groupcall Ltd.
