Why Employers Should Rethink Mandatory Qualifications
This article is part of the Training and Qualifications guide.
Mandatory qualification requirements are the conditions an employer places on a job description that a candidate must meet before being considered. Some are genuinely required by law, safety regulation, or client contract. Many others have accumulated over time through habit, template-copying, or the logic of “the last person had it.” In skills-short sectors, that second category is one of the most common reasons employers see thin candidate pools.
Why do mandatory qualifications matter for employers in skills-short sectors?
In FM, engineering, field service, and skilled trades, qualified candidates are already in short supply. When employers add qualification requirements that go beyond what the role legally or operationally demands, they narrow the pool further without improving the quality of hire. A candidate who can do the job effectively, and who can close a qualification gap within three to six months with employer support, is not a weaker hire. They are often a more motivated one.
The practical cost of over-specifying is real: roles stay open longer, interim costs rise, and teams carry the gap. It is worth distinguishing between two distinct categories of mandatory requirement:
- Genuinely mandatory: qualifications required by law, safety regulation, professional licence, or client contract. CSCS cards, gas safety registrations, electrical competency certifications. These cannot be waived and should not be.
- Habitually mandatory: qualifications that appear on job descriptions because they were on last year’s template, because the previous postholder held them, or because no one has reviewed the requirement in several years. These should be challenged regularly.
- Timing-flexible requirements: qualifications that are genuinely useful but could be completed post-hire with employer funding and a clear development pathway, without any reduction in day-one capability.
How Optio approaches mandatory qualification requirements
At Optio, we regularly see candidates who are strong matches for a role on every dimension except a single qualification that falls into the habitually mandatory or timing-flexible categories. In those cases, a rigid requirement on the job description prevents a hire that would have worked well for both sides.
Optio’s structured intent data captures what candidates in these sectors are actually qualified to do now, what they are working toward, and what development they would pursue given the right employer offer. That information sits in candidate next-move profiles, not on a CV sent speculatively to a job board. It gives employers fuller market visibility across the candidate pool: not just who is looking today, but who is considering a move and what conditions would make them act. Development pathway matching is built around exactly this: identifying candidates who could fill a role if one qualification gap were closed, and presenting that gap as a funded development opportunity rather than a hard barrier. For more on how this works, see Optio’s talent intelligence approach.
What should employers do about mandatory qualification requirements?
Start by auditing your current job description templates. For every mandatory requirement, ask whether it is legally required, whether it is safety-critical, and whether the last person who held the role actually used it day-to-day. If the honest answer to all three is no, it should either be removed or moved to a preferred qualification with a funded development pathway attached.
Build a short review question into your hiring process: “If a candidate could do 90% of this role and close the qualification gap within six months, would we consider them?” If yes, that requirement does not belong in the mandatory column. And if your answer varies depending on the seniority of the person asking, that is a sign the requirement has never been properly defined.
If you want to see how this plays out in practice across FM, engineering, and field service roles, the employers page sets out how Optio structures development pathway matching as part of a broader talent strategy.
Frequently asked questions
What is the difference between a mandatory and a preferred qualification on a job description?
A mandatory qualification means no candidate will be progressed without it. A preferred qualification is one the employer would like but will not use as a filter. Many qualifications listed as mandatory are actually preferred requirements that have never been reclassified. Reviewing the distinction regularly is a basic part of good hiring practice.
Can an employer remove a mandatory qualification requirement if it has always been on the job description?
Yes, unless the qualification is required by law, health and safety regulation, or a client contract. History on a template is not a sufficient reason to keep a requirement. If the role could be performed safely and effectively without the qualification, or with it gained post-hire, the requirement can be changed.
How does a funded training route affect the candidate pool for hard-to-fill roles?
It widens it. Candidates who hold most of the required skills but lack one qualification are a viable part of the market that hard mandatory requirements exclude. Offering a structured development pathway as part of the employer offer brings that portion of the market back into consideration without lowering the standard of hire.
Do candidates in FM and engineering expect employers to support qualifications?
Many do, particularly where qualifications are sector-standard and well-understood. Candidates who see a clear development pathway in an employer offer are often more committed to the role. It is a signal about how the employer invests in the people they hire, which matters in sectors where word of mouth shapes employer reputation.
