Your Executive Assistant Has Passed Probation. But Has the Hire Actually Delivered Value?

This is an increasingly important question for business owners, CEOs and HR leaders. Particularly when hiring an Executive Assistant (EA) or Personal Assistant (PA), whose contribution cannot always be measured by the number of tasks completed.

According to SHRM's 2025 Recruiting Benchmarking Report, only 20% of surveyed organisations measure quality of hire. Meanwhile, LinkedIn's Future of Recruiting 2025 report found that 89% of talent acquisition professionals believe measuring quality of hire is becoming increasingly important, yet only 25% feel highly confident in their organisation's ability to do so effectively.

There is a clear disconnect: businesses invest significant resources in recruitment but do not always have a reliable way to assess whether a hiring decision has delivered the expected results.

So how can you evaluate the quality of an Executive Assistant hire, which metrics genuinely matter, and what should you establish before advertising the role?

Why Filling a Vacancy Doesn't Mean You've Made a Successful Hire

Consider a business owner who has recently hired an Executive Assistant.

The candidate performed well at interview, has a solid administrative background, is confident with digital tools and gets on well with the wider team. Three months later, the business owner is pleased with their reliability: meetings are arranged, travel is booked and documents are prepared.

Yet the founder's working day has barely changed.

They are still personally prioritising meetings, chasing deadlines, reviewing supplier proposals and gathering information before making decisions.

The assistant is busy all day. So is the founder.

The question is: did the business hire someone to carry out tasks, or someone who was supposed to reduce the founder's operational workload?

These are two different objectives, requiring different capabilities, levels of authority and measures of success.

If the business genuinely needed administrative support, the appointment may well have been successful. But if the aim was to delegate responsibility for operational processes, completing individual tasks efficiently is not enough.

That is why hiring success must be measured against the original business objective, rather than the job description alone.

SHRM's 2025 Recruiting Benchmarking Report found that just 20% of surveyed organisations used quality-of-hire metrics, compared with 27% in 2022.

The research covered US organisations, with 2,371 respondents taking part, although the number of responses varied across individual measures.

A further figure from SHRM's 2026 benchmarking research is also worth noting: the median time to fill a non-executive vacancy was 39 calendar days. The report drew on data from more than 4,600 organisations.

This does not mean that recruiting an Executive Assistant in the UK takes exactly 39 days. However, it illustrates the scale of resources organisations can commit to recruitment before a new employee has even started.

LinkedIn's Future of Recruiting 2025 report, which included a survey of more than 1,000 talent acquisition professionals, adds further context:

✅ 89% believe measuring quality of hire will become increasingly important.

✅ 25% feel highly confident in their organisation's ability to measure it effectively.

✅ 93% believe accurately assessing candidates' skills is important to improving hiring quality.

These findings come from separate studies with different samples, so they should not be treated as directly comparable measures of the same market.

Nevertheless, they support an important management principle: recruitment speed and the quality of a hiring decision should be assessed separately.

Finding a candidate quickly is one recruitment objective. Establishing whether that person meets the organisation's actual business needs is a broader responsibility shared by the hiring manager and HR.

Consider a typical Executive Assistant job description:

“Diary management, travel arrangements, document preparation, supplier liaison and ad hoc support to the CEO.”

The responsibilities are clear. But they tell us very little about what success in the role should look like.

For example, “supplier liaison” might mean passing messages between the CEO and external providers. Alternatively, it might involve gathering requirements, comparing commercial terms, monitoring deadlines and preparing a recommendation.

The first requires organisation, reliability and strong communication.

The second also demands analytical thinking, commercial awareness, risk assessment and the ability to exercise judgement within agreed boundaries.

If the business expects the second outcome but assesses candidates primarily on their administrative experience, the risk of a poor match increases.

The mismatch may not become apparent at interview. It may emerge several months later, when the CEO realises they are still doing much of the work themselves.

This is why a role profile should begin with the business outcome the organisation wants to achieve, rather than simply a list of duties and software requirements.

How many recurring situations can the assistant manage without seeking additional approval?

For example, they may independently arrange routine business travel within an agreed budget, while escalating unusual itineraries or significant additional expenditure.

The aim is not to eliminate questions. It is to assess whether the employee understands which decisions they can make and which require executive approval.

Does the executive receive raw information, or a properly evaluated set of options that supports a decision?

Instead of forwarding five supplier quotations with different terms, a strong assistant might provide a comparison of costs, timescales, limitations and a reasoned recommendation.

One useful measure is the proportion of submissions accepted without substantial reworking.

Are commitments met on time? Does the employee flag risks before they become problems? Does the executive still need to chase every stage of a task?

It is useful to record not only missed deadlines but also their causes: employee error, changing priorities, external dependencies or insufficient authority.

Which processes no longer require the executive's constant involvement?

This should include not just the time spent carrying out tasks, but also briefing, approving, checking and correcting work.

Does the actual level of responsibility match what the organisation originally hired for?

Sometimes an assistant performs their duties well, but the business has evolved and now needs someone with project coordination or operational management capabilities.

That may call for a change to the role rather than a judgement that the employee is underperforming.

One of the clearest ways to assess the value of an EA is to compare how much time the executive spends on specific processes before and after delegation.

Consider a hypothetical example.

Before hiring an assistant, a founder spent approximately 12 hours per week managing their diary, arranging travel, dealing with suppliers and following up on outstanding tasks.

After the hire, the assistant took over much of the day-to-day execution. However, the founder still spent:

✅ 2 hours briefing the assistant and clarifying requirements.

✅ 2 hours approving decisions.

✅ 1.5 hours reviewing work and making corrections.

That amounts to 5.5 hours per week.

The actual time released is 6.5 hours, not the full 12.

This is a positive outcome, but it demonstrates that delegating tasks does not necessarily remove the executive from the underlying process.

A simple calculation is:

Time released = executive time spent on a process before hiring − executive time spent on the same process after hiring.

There are two important qualifications.

First, comparisons must account for changes in workload. If the number of projects has doubled, a straightforward comparison of hours could be misleading.

Second, time savings should not come at the expense of accuracy, increased costs or a loss of control over important decisions.

For that reason, time released should be assessed alongside quality, reliability and cost.

If the business wants to calculate the financial return, it should also consider the cost of the working time involved, rather than simply the number of hours saved.

Instead of relying on a subjective impression that the new assistant “seems to be doing well”, agree on measurable milestones before they join.

This is not a universal probationary assessment standard. It is a practical framework for understanding how the role begins to create value.

First 30 Days: Understanding the Business

At this stage, the priority is to assess how well the assistant is learning the organisation's processes and understanding the executive's expectations.

✅ Understands the executive's main priorities and communication preferences.

✅ Knows which decisions can be made independently.

✅ Has learnt the relevant systems and document-handling procedures.

✅ Can complete routine tasks without repeated explanations.

Expecting complete autonomy in complex matters during the first month may be unrealistic. The emphasis should be on the quality of onboarding and the employee's ability to learn.

60 Days: Autonomy and Consistency

The next stage is to assess whether the assistant can take ownership of recurring processes.

✅ Routine tasks are completed within agreed deadlines.

✅ The need for detailed instructions is decreasing.

✅ Significant risks are raised before they become urgent problems.

✅ Documents and recommendations require fewer substantial revisions.

At this point, the difference between completing individual instructions and taking responsibility for a process should start to become visible.

90 Days: Measurable Business Impact

By the third month, it is time to revisit the original reason for hiring.

✅ Which processes have been fully or partially delegated?

✅ How much time does the executive still spend overseeing them?

✅ Has the number of errors or requests for rework changed?

✅ Which decisions can the assistant now prepare independently?

✅ Does the actual level of responsibility match the expectations set for the role?

For more complex Executive Assistant positions, a meaningful assessment may require longer than 90 days. The three-month mark should therefore be treated as a useful review point, not a definitive prediction of future performance.

One less obvious reason for an unsuccessful hire is a mismatch between the executive's expectations and the employee's actual authority.

Imagine a company recruiting a proactive Executive Assistant who can anticipate needs and work independently.

During the interview process, the hiring manager looks for initiative, experience supporting senior executives and sound decision-making.

Yet once the employee starts, every diary change, supplier selection and communication with a business partner requires the CEO's personal approval.

The assistant cannot operate independently, despite that being one of the qualities they were hired for.

The CEO sees a lack of initiative. The assistant believes they are respecting the limits of their authority.

This may not be a recruitment failure at all. It may be a failure in how the role was designed.

Before recruiting, the organisation should therefore establish:

✅ Which outcomes the employee will be responsible for.

✅ Which decisions they can make independently.

✅ What budgets and restrictions apply.

✅ Which matters must always be escalated.

✅ How their performance will be assessed.

Without this clarity, even an experienced Executive Assistant can find themselves in a position where they are expected to show initiative but are not permitted to exercise judgement.

LinkedIn's Future of Recruiting 2025 research found that 93% of surveyed talent acquisition professionals consider accurate skills assessment important to improving quality of hire.

For Executive Assistant roles, this matters particularly because a confident account of previous experience does not necessarily reveal how someone responds to incomplete information, competing priorities or unexpected problems.

A structured interview can therefore be strengthened with a realistic scenario.

For example:

“The CEO has an important meeting with a business partner tomorrow. Late this afternoon, you discover that some essential briefing materials are missing and the colleague responsible is unavailable. What would you do?”

The aim is not to identify one perfect answer, but to understand the candidate's reasoning.

✅ Do they identify which information is genuinely essential?

✅ Do they look for alternative sources or relevant colleagues?

✅ Do they recognise what they can resolve within their authority?

✅ Do they present options and explain the associated risks?

✅ Do they know when and how to escalate the issue?

A strong candidate may not produce a flawless response immediately. What matters is their ability to structure an ambiguous situation, assess the consequences and act within appropriate boundaries.

For consistency, candidates applying for the same position should receive comparable scenarios and be assessed against predefined criteria.

This helps reduce the influence of personal impressions and allows employers to compare relevant capabilities more objectively.

If the new hire has not delivered the expected results after several months, starting another recruitment process may not be the right first step.

The organisation should identify the underlying cause.

Scenario One: The employee cannot perform tasks that should be within their stated experience. Review the original assessment process, onboarding, feedback and actual performance.

Scenario Two: The employee completes tasks but shows little independence. Check whether decision-making boundaries have been established and whether the executive is genuinely prepared to delegate responsibility.

Scenario Three: The assistant performs well, but the CEO remains overloaded. The business may have recruited an administrative assistant when it actually needed someone with project coordination or operational responsibilities.

Scenario Four: The employee has developed, but the role has not. It may be time to review responsibilities, performance measures and remuneration.

In all four cases, the situation can look similar from the executive's perspective: the hire has not met expectations.

But the appropriate response will be different.

Recruiting a replacement without addressing the underlying cause risks recreating the same problem with a different employee.

Before recruiting a Personal Assistant, Business Assistant or Executive Assistant, the hiring manager and HR team should agree on the purpose and scope of the role.

Start with a brief review.

✅ Which processes currently require the executive's personal involvement?

✅ Which can be delegated without losing appropriate oversight?

✅ What level of autonomy does the role genuinely require?

✅ Which skills are essential from day one, and which can be developed through onboarding?

✅ What results should be visible after three months?

✅ What resources and authority will the organisation provide?

This helps prevent a common contradiction: looking for an independent professional while creating a role in which independent decisions are practically impossible.

It also enables recruiters to assess candidates against meaningful criteria rather than simply matching CVs to a list of duties.

Effective Executive Assistant recruitment starts with understanding which responsibilities the executive needs to delegate and what successful support should look like.

At SMART AND TALENTED, we recommend starting with a complimentary consultation to assess your Executive Assistant requirements.

This provides an opportunity to clarify:

✅ Which tasks and processes would be most valuable to delegate.

✅ What level of assistant the business actually needs.

✅ Which competencies should be essential selection criteria.

✅ How to define the role around the executive's real priorities.

Following the consultation, we can discuss a tailored recruitment process for a Business Assistant, Personal Assistant or Executive Assistant.

A successful hire is not simply someone who accepts the offer and passes probation. It is someone who can take ownership of clearly defined responsibilities and deliver dependable results.

That is what businesses should measure before declaring a vacancy successfully filled.
