Manageability

Collaboration

Proportionality

Triangulation and typicality

Source: Independent Schools Inspectorate

Triangulation and typicality

• ISI will contextualize and test evidence to come to valid and reasonable conclusions (triangulation)
• ISI will gather evidence from a plethora of sources
• ISI will conside the typicality of the school they inspect through triangulation

Manageability

• ISI is mindful not to disrupt the school
• ISI will not expect schools to produce specific documentation prior or during the inspection
• ISI will view pupil's current work and not expect to collate work prior to inpsection
• ISI may request to see certain files to evaluate the day-to-day running of the school
• ISI will collaborate with schools to attempt to find suitable times for inspection

Proportionality

• ISI will make judgements on schools professionally, taking scale and impact of errors into consideration
• When there are just minor errors, ISI will take a proportionate approach (vice-versa is true for systemic difficulties)
• ISI will create a guided action plan to remedy errors

Collaboration

• ISI will work collaboratively with school leaders to ensure the smooth-running inpection
• ISI will liaise regularly with school leaders to keep in touch with ongoing inspections
• ISI will offer school leaders the ability to be involved with some inspection activities, like joint lesson walks. These activites are helpful for providing context to evidence
