Becoming an IB World School is one of the most demanding commitments a school can make, and the process is deliberately rigorous. Many leaders enter it underestimating the time, the documentation, and the institutional change involved — and then stall partway through. This guide lays out the path clearly, so you can plan it with your eyes open.
It is written for heads, boards, and coordinators weighing authorization or already inside it. It does not replace the IB's official guidance; it explains the shape of the journey and where schools most often get stuck.
The path in brief
Authorization moves through distinct phases. A school first expresses interest and becomes a candidate; it then works through a candidacy (consultation) period; and finally it submits a request for authorization, culminating in a verification visit. Only after that does it become an authorized IB World School able to deliver the programme.
The whole journey commonly takes two to three years. The variable is not the IB's timeline — it is how ready the school is when it starts.
The candidacy and consultation period
This is the heart of the process, and where most of the real work happens. During candidacy the IB assigns the school a trained IB educator to serve as its consultant. The consultant is an advisor: they build an understanding of where the school stands against the requirements for authorization, and they guide the school in creating and refining its action plan.
A point worth setting expectations on early: the IB consultant provides a defined amount of remote support each candidacy year plus a consultation visit. That support is meaningful but bounded — it is advisory, not a delivery resource. The school itself carries the substantive work.
While the consultant advises, the school must be developing or updating its required policies, planning and documenting its IB curriculum and implementation, ensuring facilities and resources meet the IB's programme standards and practices, and completing the professional development its staff are required to undertake.
What schools consistently underestimate
1. The professional development requirement
By the end of candidacy, the school must show evidence that it has met all PD requirements set out in the programme-specific guides to authorization. PD takes time and money to schedule, and a school that leaves it late can find its whole timeline held hostage by training that hasn't been completed.
2. The policy and curriculum documentation
Authorization is, in large part, an exercise in demonstrating coherence on paper — assessment policy, language policy, inclusion policy, a documented curriculum aligned to programme standards. Schools that already operate coherently find this confirmatory. Schools that operate informally find it transformational, and slow.
3. The hidden costs of the consultation visit
Beyond IB fees, schools incur direct costs around the consultation visit — and in several regions, including Africa, Europe and the Middle East and Asia-Pacific, the school also covers the consultant's accommodation, which IB fees do not include. These are small relative to the whole, but they surprise leaders who budgeted only for the headline fees.
The milestones that gate progress
To move from consultation to the next phase, a defined sequence must be completed: the school and consultant agree visit dates, the IB schedules and conducts the consultant visit, the IB issues the visit report, the school determines it meets the requirements for authorization (including completed PD), the school informs the IB it intends to apply, the consultancy formally ends, and the IB issues its end-of-consultancy report.
Each is a gate. A school cannot move forward by working harder on the next stage; it has to clear the current one.
Where schools get stuck
In practice, the stalls cluster in three places:
PD left too late, which blocks the readiness determination.
Curriculum documentation that exists in teachers' heads but not on paper, which the process forces into the open.
Leadership bandwidth — authorization is a major project layered on top of running a school, and where no one owns it as a named responsibility, it drifts.
The schools that move through cleanly treat authorization as a project with an owner, a timeline, and a review rhythm — not as something that will happen alongside everything else.
Where to start
1. Read the programme-specific guide to authorization for the programme you intend to offer. The requirements differ by programme, and the guide is the source of truth.
2. Map your PD requirement early and schedule it first, not last.
3. Audit your existing policies and curriculum documentation against the programme standards and practices before the consultant arrives. The further along you are, the more useful the consultant's bounded hours become.
4. Name an internal owner for the project with the authority and time to drive it.
The realistic timeline
Plan for two to three years from expression of interest to authorization, and treat that as a floor rather than a target. The schools that hit the shorter end are the ones that arrived organised — coherent curriculum, completed PD, clear ownership — and used the consultation period to confirm readiness rather than to build it from scratch.
