IPD develops the specialist knowledge and skills needed for structural engineering practice. It takes your learning from the educational base towards professional qualification.
The shape of it
Two things in that description are worth dwelling on, because they change how people plan.
"Progressive." IPD is not a fixed number of years followed by an application. It is a movement from doing work under supervision towards carrying responsibility and making independent judgements, which is what the three minimum standards describe. What determines readiness is where you have got to on that movement, not how long you have been going.
"All relevant experience may be considered, including pre-graduate experience." Candidates routinely discount a placement year, part-time work during study, or a period in a related discipline. If it developed the knowledge and skills the Core Objectives describe, it can be put forward.
Broadening, then deepening
The guidance sets out a shape that matches how careers go: early on you broaden (several project types, several materials, several stages) and later you deepen, until you can work unsupervised and advise others in the areas set at Ability.
That has a practical consequence. If you have spent four years doing one thing very well, you may be closer to the Ability standard in one objective and further from the Experience standard in five others than someone with a messier, broader record. It is worth auditing early rather than assuming that time served covers it.
What IPD produces, in the end
- 01
Records kept as you go
Whatever route you take, evidence of progress against each Core Objective. On the individually managed route that means quarterly report forms and a progress summary record.
- 02
IPD final report forms
One for each of the ten Core Objectives, completed once you have satisfied the requirements. On the individually managed route these are signed by your personal mentor.
- 03
A two-page experience report
Your roles and responsibilities over the course of your career, submitted with the forms as a single document when you apply.
- 04
A portfolio of work
Up to 300 pages, sub-divided by Core Objective, sent directly to your two reviewers before the interview.
Questions to ask yourself
- Which route am I on, and have I chosen it deliberately?
There are three, they suit different situations, and drifting into one by default is how people end up with records that do not support an application.
- Am I recording evidence as I go, or reconstructing it later?
The detail that makes evidence convincing (the option you rejected, the number you checked) is gone within a year.
- Have I counted my pre-graduate experience?
The guidance explicitly allows it, and candidates routinely leave it out for no reason.
