5The hard call
Late August. The vendor has added captions support and an adjustable timer, and says the figures will not be keyboard-operable before the licence ends. The technicians say the spoken explanation at the bench is a safety check and cannot be dropped.
- Essential Requirements and the Limits of Flexibility — the most demanding judgement in the field: when flexibility preserves what is being measured, and when it alters it.
- Access in Studio, Shop and Lab-Based Learning — protecting the safety requirements that are genuine while examining the ones that are only habit. The check is genuine; speech is the habit.
- Eliminating Construct-Irrelevant Barriers in Assessment — the validity principle underneath all of it: a result should reflect capability, not incidental obstacles.
- Accessible Live and Virtual Facilitation — access in the room: how a technician conducts a check with a learner who signs through an interpreter, or who answers through a device, at the pace the device sets.
- Faculty Development That Changes Accessible Practice — the technician’s brief is faculty development in miniature: what they need to be able to do, in the room, on the day.
- Funding Design for Accessible Learning Programs — writing the budget line so that access is the deliverable. A rebuild funded as “accessibility fixes” is cut first; one funded as the module itself is not.
The associate dean decides to rebuild the figures and funds the work. The platform’s drag-and-drop activity is replaced, for every learner, by an activity the unit authors and hosts in the learning management system: the same hazard symbols, the same diagram, operable by keyboard and by pointer, with each control named so that a screen reader announces it, and with a single-pointer alternative to dragging as the current guidelines require (source 23). The platform’s version is retired rather than kept as a parallel route. The reasoning is recorded, with the vendor’s written statement, for the licence renewal.
The associate dean reasons the practical through with the technicians rather than deciding it for them. Validity belongs to the interpretation of a score, not to the test itself (source 9), so the question is what the spoken check is taken to establish. Put in plain words, as Meiorin asks it: what does the technician need to know before the learner picks up the glassware? The technicians answer it themselves: that the learner knows the step, the hazard, and the response. Speech is how they have always learned that, not what they are checking. The knowledge is a bona fide requirement of the standard; the channel is construct-irrelevant variance (sources 3, 8). The check stays, for every learner. The learner who signs gives it through an interpreter booked for the session; the learner who uses a speech-generating device gives it through the device, and the technician waits for the device. Neither is a lowered standard. The brief that goes to the technicians says so in those words, and says how long to wait, how to address the learner and not the interpreter, and where the procedure sheet in advance came from.
Where practice disagreesWhether a separate accessible version of the figures would have done. The guidelines permit a conforming alternate version, provided it is equivalent and reachable (source 23), and some faculties would have built one for the learners who needed it and kept the platform’s version for the rest. This path retires the original, on a judgement rather than a rule: two versions of a safety module diverge over time, the one fewer people use is the one that stops being maintained, and a learner sent to the alternate version is sent to a different module. One version, built to work for everyone, is the design the duty points to. A decision reasoned this way is an argument that links the performance to the inference drawn from it (source 10), and it is written down so that the next leader does not have to make it again.
