PUBLISHED CRITERIA / planning-information-1.0

What the rating measures.

This selection considers programme substance and editorial context. It draws on official event information and the editorial questions shown beside each entry.

A snapshot of verifiable planning information on 2026-09-22.

One verified checkpoint equals one point; ten points are available. Every eligible edition receives the same checks. A higher count means more planning details were established in the reviewed sources. It does not establish better speakers, networking, value, attendee satisfaction or business results.

The ten equally weighted checks +
  1. Edition and dates

    A named edition, explicit year, and start and end dates. An explicitly single-day event qualifies.

  2. Delivery location

    An attendance mode and a named venue with city, or an identified online platform or access route.

  3. Programme example

    At least one edition-specific session title with a substantive description. Broad themes alone do not qualify.

  4. Daily timetable

    The main programme has start and finish times for every advertised day, with a time zone or explicit local-time convention.

  5. Named contributor

    At least one contributor is assigned to this edition with a name, affiliation or professional role, and event or session role.

  6. Audience and eligibility

    The intended audience and public, application-based or invitation-only attendance rules are stated.

  7. Standard admission cost

    The individual non-member standard pass has an amount, currency, mandatory fees and tax treatment. Explicit free admission with eligibility qualifies; group rates do not substitute.

  8. Pass inclusions

    The same pass lists main-programme access and the treatment of advertised separately ticketed components.

  9. Refunds and transfers

    Applicable public terms explain both attendee cancellation or refunds and ticket transfers, including restrictions.

  10. Organiser and contact

    A named organiser provides a public route for event or booking questions.

We reviewed the next dated organiser-run edition of each listed series, including an ongoing edition, at the cutoff. Separate sub-brands and independently run community events are excluded. The underlying cohort has 21 series; this publication selects 5 for programme substance and editorial context. It is not an exhaustive world ranking. Selection itself is editorial and includes the affiliated event.

Order follows verified counts, highest first. Equal counts share a competition rank (1, 1, 3); alphabetical display order does not break a tie. Unverifiable or conflicting edition dates mean “not rated”, not zero. No ownership or payment adjustment enters the calculation.

Research scope and limitations +

Each audit uses up to five substantive official pages, prioritising edition, programme, contributors, admission and linked terms/contact information. Embedded widgets form part of their parent page. We made a follow-up attempt where dynamic content did not load. A missing point means evidence was not established within this review, not that the organiser does not provide it elsewhere.

Only verified checks earn a point. Missing, inaccessible, historical and conflicting evidence is identified separately. Organiser statements establish what is published, not whether promises were delivered. Future editions often have less complete information; lead time and the fixed source budget limit comparisons. We did not collect comparable attendee-review or outcome data.

This dated snapshot is not a live ticket feed. Check the official source before booking. Evidence should be refreshed within 30 days, or seven days when an event is within 30 days, before issuing a new current rating. Corrections require updating the assessment and every affected publication.

Publisher relationship and shared research +

The Convention Letter and Open Summit share common ownership. These publication brands reuse one assessment dataset, so matching results are not independent corroboration. This is an internal publisher audit, without independent certification. Open Summit’s additional city guide is an affiliated commercial profile; it contributes no extra rating points.
