Your profile decides what you see
The subject and year-group pickers are not a catalogue of everything MESO supports — they are filtered to what you told MESO you teach during profile setup. If it is still missing after that, the specification is not loaded yet. Tell us at contact@mesolab.ai — subject coverage is prioritised by what schools actually ask for.Checking what is available
The picker in the create-unit flow is the authoritative list for your account, and it is always current. This page deliberately does not reproduce a list of subjects, because a copy in documentation goes stale the moment a specification is added.Junior Cycle and Senior Cycle are separate
A subject can exist at both cycles and they are distinct in MESO, with different specifications, different learning outcomes and different assessment methods. History at Junior Cycle and History at Senior Cycle are not the same subject and will not plan the same way. Choosing the year group first, as the create-unit stepper does, is what settles which of the two you are working in.Levels
Where a specification distinguishes levels, that distinction lives in the
specification content MESO plans against rather than in a separate picker. Check
the outcomes selected on a unit’s Overview if you need to confirm what a plan
was built from.
