Use this material to examine your own work. Confirm current requirements, forms and dates with IStructE before applying.
If you fail three or fewer objectives, the re-interview covers those objectives. Failing four or more requires the whole interview to be repeated.
The three-year window is the part to plan around
No limit on attempts sounds generous, and it is. The constraint that bites is the three years: clear the failed objectives inside it and you resubmit only what failed; miss it and you are writing all ten forms again.
If the failure was an experience gap rather than a writing one, three years is not as long as it sounds. Start the development plan the week the result arrives, not the month before the next attempt.
Read the feedback literally
You are told which objectives did not meet the standard. That is precise information, and it is worth taking at face value rather than reinterpreting it.
A common mistake is to assume the reviewers meant something adjacent: that "management" really meant the interview went badly overall. It did not. Take the named objectives, go back to the standard for each, and ask the gap-analysis question: is this a writing gap, an evidence gap, a level gap, or an experience gap? The four have completely different remedies.
Appeals are narrow
The Institution operates an appeals procedure, but the grounds are limited. An appeal is not a second opinion on whether you met the standard: that judgement belongs to the reviewers and the panel. It concerns things like extenuating circumstances occurring immediately before or during the application process or the interview.
If you think the process went wrong, contact the Institution and ask about the appeals procedure directly. If you think the judgement went against you, the route is a re-interview, not an appeal.
The other clocks
Two rules connect the interview to the examination, and they catch candidates who pass one and stall on the other:
- Postpone the examination for three consecutive years after the interview and, on eventually passing it, you must apply for a full PRI again.
- The examination must be passed within five years of completing the interview, with no gap longer than three years between attempts.
The Engineering Council normally requires registration within three years of completing the PRI, which is where both rules come from: the point is that the competence demonstrated at interview has to still be current.
What a failure means in practice
| Situation | What is repeated | What you resubmit |
|---|---|---|
| Three or fewer objectives failed | A re-interview on those objectives only | Evidence and forms for the failed objectives, within three years |
| Four or more objectives failed | A full re-interview | The whole submission, as a new application |
| More than three years elapse | A re-interview covering all ten | IPD final report forms for all ten Core Objectives |
