TheCore Standard. Live demo
A 3-minute demo for employers

See how a candidate actually works. Before you hire.

If you are hiring an EA right now, you have a shortlist that all looks right on paper, and an interview process that only tells you so much. The Core Standard shows you how each candidate actually thinks under the pressure of a real working day, so you decide on evidence, not on who presents best. Take the candidate's seat below, then see the report that lands in your inbox.

If you are hiring an EA right now

The shortlist looks great. That is the problem.

Several CVs that all look right. Interviews that only tell you so much. A hire that, if it is wrong, costs you months and a lot of goodwill to unpick. Whether you hire through an agency or direct, the interview rewards whoever presents best, not whoever will do the job best. Use it before interviews to decide who is worth your time, or after them to settle a close call. Here is where it helps:

Choosing between finalists
Two strong candidates, one seat. Settle it on evidence of how they actually work, not on who interviewed better on the day.
Hiring direct
You have sourced the candidates yourself. This gives you the vetting a specialist EA agency would run, on your own shortlist, with a report in 48 hours.
A CV you cannot quite read
Strong on paper, but a career break, a sideways move, or a real step up. See how they perform before you commit to three interview rounds.
A promotion or internal move
Before you move an EA into a bigger seat, check they are ready for the judgement the next level demands.
1The candidate's seat

It's 8:14am. The inbox just landed.

This is one module of the assessment, Inbox Triage. The candidate has minutes, not hours. For each message, they decide: action now, hold, escalate, or decline, and then explain why. Try it yourself. There is no single right answer. We score the reasoning behind the ranking, not the ranking itself.

You are EA to Diane Ashworth, CEO, Ashcombe Group
10:00 on the clock
Five messages arrived while Diane was on a flight. She lands in ninety minutes. What do you do with each, and in what order?
Board Secretary07:52
Re: Q3 board pack, one figure looks off
"Diane, the revenue slide in the pack going out at 9am doesn't match the finance summary. Can someone confirm before it's circulated to the non-execs?"
The reasoning we score Actioned immediately, and correctly read this as the critical path: a wrong figure reaching non-execs is hard to walk back. They held the pack, flagged finance, and protected Diane before she even landed.
PrioritisationJudgement
Diane's husband08:05
Anniversary dinner Friday?
"Can you get us the corner table at the usual place for Friday, 8pm? Don't tell D, it's a surprise."
The reasoning we score Held, then quietly actioned once the board issue was contained. It matters, and it is personal to the principal, but it is not time-critical at 8am. Note the discretion: a surprise stays a surprise.
PrioritisationPartnership
Junior colleague, Marketing08:09
Can you approve this spend? Diane usually does
"Need sign-off on a 4k campaign booking by lunch or we lose the slot. Diane approved a similar one last month so I assume it's fine?"
The reasoning we score Declined to approve in Diane's name, and said so in writing. Knowing the edge of your authority is judgement. They offered a clean path instead: a two-line summary ready for Diane to approve in one tap on landing.
JudgementCommunication
Key client, external08:11
Disappointed after yesterday's call
"Frankly not what we expected. I'd like to speak to Diane directly today, or we may need to reconsider the retainer."
The reasoning we score Escalated, but did the work first: a holding reply in Diane's voice that lowered the temperature and bought time, plus a one-line brief so Diane could call back fully informed. Bad news, handled with grace.
CommunicationPartnership
Newsletter, industry weekly08:13
10 productivity hacks for busy executives
"This week's roundup, plus a webinar invite for next Thursday..."
The reasoning we score Declined, in seconds, and moved on. Composure under a loaded inbox is partly knowing what deserves none of your attention. The weak candidates spend real minutes here.
Prioritisation

Made your calls on each message? Now see how a strong candidate handled them, and the reasoning we score.

2Not a quiz. We score the why.

The judgement lives in what they write.

There is no multiple choice, and no hidden right answer to click. Across the day the candidate is asked what they would do and, every time, why. The responses are written in their own words, and the reasoning is where a capable EA separates from a good guesser. Two more modules from the same day:

Access & Discretion Judgement Partnership
A senior colleague asks you, in confidence, to quietly share Diane's calendar for the next fortnight, "so we can find time without bothering her." What do you do, and why?
The candidate wroteI wouldn't share the full calendar. It is not mine to open up, and "without bothering her" is usually a sign the request should go through her. I would offer to find a slot myself against her availability, or check with Diane whether she is happy for me to share. If it was pushed, I would say no politely and let Diane know it had come up.
What it reveals: the decision is easy, the reasoning is not. They protect the principal, notice the soft pressure in "without bothering her," and keep the relationship intact. None of that surfaces in an interview.
Judgement with AI Judgement Communication
AI has drafted this client reply for you: "Hi, yes, we can absolutely guarantee delivery by Friday, and a full refund if not." Would you send it? Why?
The candidate wroteNo. It commits Diane to a guarantee and a refund that are not mine to promise, and I cannot verify Friday is realistic. I would take out the guarantee, confirm the timeline with the team first, and send something honest: that we are aiming for Friday and I will confirm by end of day. The AI got the tone right and the risk wrong.
What it reveals: anyone can use AI. We test whether they catch what it gets wrong. Here they spot an over-promise the model made happily, and explain the fix. That is AI fluency, and it is a real EA competency now.

Illustrative prompts and answers. In the live version these become real, anonymised candidate responses.

3How good is good?

The same message. Three levels of EA.

The same dimensions are scored at every level. What scales with the seat is sophistication. You choose the level when you commission the assessment, and the candidate is measured against that level, not placed somewhere on a ladder. Here is how three candidates, assessed at three different levels, each replied to that unhappy client. All three are competent. Watch what the higher levels add.

The message they were answering "Frankly not what we expected. I'd like to speak to Diane directly today, or we may need to reconsider the retainer."
L1
Operational EA
"Thank you for your note, and I'm sorry yesterday's call fell short. I've flagged this to Diane as a priority and she will come back to you personally today. I'll make sure she has the full picture before she does."
Solid and correct. Acknowledges, does not over-promise, escalates cleanly, and buys the principal time.
L2
EA to Senior Leadership
"Thank you for being straight with me, and I'm sorry yesterday didn't land as it should have. Diane will want to speak with you herself, so I've held time in her diary this afternoon for a proper conversation, not a rushed one. Is there anything specific you'd like her to come prepared to address? I'll make sure she has it."
Adds anticipation. Holds concrete time, invites the real issue, and controls tone. Reads as a partner, not a gatekeeper.
L3
Executive Business Partner
"Thank you for telling me directly. You matter to us, and a conversation about the retainer is one Diane will want to have properly, not defensively. I've held time with her at 4pm today, and I'll move it to suit you if that's easier. So the call moves things forward, it would help to know the one or two outcomes that would make this right for you. I'll brief Diane fully so she arrives ready to act on them."
Adds commercial judgement. Reads the retainer risk, reframes a threat into a solvable conversation, and sets the principal up to act, not just apologise.

Illustrative drafts, shown so you can see the format. These are ready to swap for real, anonymised candidate answers.

4One working day, built from scenario modules

That was one module. A full assessment runs six to eight.

Every candidate sits the same core scenarios inside a session clock. Every module feeds the scored dimensions. The more senior the seat, the more the day layers on.

5What lands in your inbox

The report. Readable in ten minutes, defensible in a board meeting.

Within 48 hours you receive a full assessment report: how the candidate measured against the level you commissioned, a clear recommendation, an overall score, a mark on each of the six dimensions and every scenario backed by evidence from the simulation, and a written note signed by Lily Shippen. It is built to be read in ten minutes and acted on the same day, so you can make the hiring decision now and defend it in a board meeting later. Here is a real, anonymised sample.

CS.The Core Standard · Assessment Report
Level 2 · EA to Senior Leadership

A measure of judgement, not just experience. This report sets out how the candidate approached a live, unscripted day in an executive office, measured against the level you are hiring for: where they showed real strength, and where to focus next.

The result

You choose the level when you commission the assessment. The candidate is measured against that level and nothing else, so the report answers the question you actually asked: are they ready for this seat?
Assessed at
Level 2 · EA to Senior Leadership
A true right hand. Anticipates, prioritises, manages stakeholders, and holds things together under pressure. Alex was assessed at this level for a seat supporting a divisional managing director.

Alex met the Level 2 standard across the day, and was at their strongest in the moments that carried the most risk. They guarded the principal's reputation under pressure, spoke for her to a frustrated client with a measured, on-message reply, and were disciplined with sensitive information and with AI. Six of the eight scenarios scored above the Level 2 benchmark. The one clear area to build is clearing a full inbox at pace.

74/ 100
Strong hire at this level. Above the Level 2 benchmark overall, with five of the six dimensions clear of it. The development edge is prioritisation under a full load, and it is a coaching point rather than a reason to pause.

The six dimensions

Each dimension is scored out of 100, drawn from what the candidate did and wrote in the simulation, not from a CV. The shape matters as much as the average.
Situational read
80
Caught the buried risk in a full inbox and the tone shift from a frustrated client.
Communication and influence
82
Spoke for the principal to a difficult client without overpromising; register matched every audience.
AI fluency and judgement
78
Spotted an AI draft that over-promised a guarantee, and corrected it before it went out.
Partnership and managing up
79
Protected the principal before she landed, and anticipated what she would need without being asked.
Prioritisation
66
Sound calls, but slowed by a full inbox at pace. The clear area to build.
Execution
70
Critical deliverables complete; one lower-priority loop left open when the clock ran out.

Every scenario, scored

All eight modules, each scored out of 100, with the reviewer's one-line read. Six scored above the Level 2 benchmark.
Inbox Triage
A five-item inbox under a hard clock. Sound calls, but the slowest module, and the clear area to build.
66 / 100
Simultaneous Demands
Three urgent asks at once. Ordered them well, though one hand-off could have gone sooner.
72 / 100
Access & Discretion
A confidentiality request with soft pressure inside it. Declined cleanly in writing. Sound instinct.
80 / 100
Rebuilding the Day
The diary fell apart mid-morning. Re-sequenced under pressure without dropping what mattered.
76 / 100
Representing the Principal
Live drafting across three audiences. Tone landed each time; the client reply was the standout.
84 / 100
A Sensitive Situation
A delicate interpersonal moment. Handled with tact and an eye on the principal's reputation.
81 / 100
Judgement with AI
An AI draft with a buried flaw. Caught the over-promise and corrected it rather than shipping it.
78 / 100
Reading the Numbers
A dashboard with a decision inside it. Surfaced the two things the principal needed, in the right order.
77 / 100

Reviewer note

Written by the practising EA recruiter who reviewed the work. Not machine-only.

Alex ran the morning the way you want an EA to run it. The board-pack error was the trap in this assessment, an easy thing to skim past under a full inbox, and they caught it inside the first few minutes and understood immediately why it mattered more than anything else on the screen. That is the instinct that separates a capable EA from an impressive one.

What stood out most was the discretion. Faced with a spend approval framed to make saying yes the easy option, they declined cleanly and put the decision back where it belonged, in one tap for the principal on landing. They did the same with the personal request: held it, protected the surprise, actioned it once the urgent work was contained. You cannot teach that read on where your authority ends. Communication and influence is their strongest dimension, and it shows in the client holding reply, which lowered the temperature without promising anything that wasn't theirs to promise.

The one area I would probe in a final conversation is execution under the very hardest time pressure. Everything critical was complete, but one lower-priority loop was left open when the clock ran out. Nothing concerning, and arguably the right call, but worth a question on how they close out a day that overruns. On balance, a strong hire for a senior-leadership seat, and someone I would be comfortable putting in front of a demanding principal.

Recommendation: proceed to final interview
A strong Level 2 result, and a confident shortlist call. Probe prioritisation under a full load in the final conversation; otherwise, a strong hire.
Decide now. Defend it later.
Everything a hiring decision needs sits on one page: the recommendation against the level you set, the overall score, a mark on every dimension and every scenario, the evidence behind each, and a named specialist who reviewed it. Enough to make the call this week, and to stand behind it in a board meeting six months from now.
