Free Light Audit vs. Deep Audit: Which Does Your School Need?

Not every school needs a deep audit. That is worth stating clearly, given that it comes from the people who built the deep audit.

IRIS5 offers two assessment levels because different schools are in different situations. A school that's curious about where it stands doesn't need the same depth as a school preparing a strategic case for the board. Using a deep audit when a light one would do is like commissioning a full structural survey because you noticed a dripping tap. It's not wrong, exactly. It's just more than you need right now.

So here's an honest comparison. What each level gives you, what it can't tell you, and how to decide.

The Light Audit: Your 20-Minute Health Check

The light audit is questionnaire-only. You answer a set of structured questions across all five IRIS5 dimensions: financial health, enrolment and market position, governance and compliance, operational effectiveness, and AI exposure and opportunity. It takes about 20 minutes. It's free.

What you get back is a RAG-rated snapshot. Red, amber, green across each dimension, based entirely on your responses. Think of it as a perception check. It tells you what your leadership team believes about the school's health.

That is genuinely useful. Most schools have never sat down and systematically assessed themselves across all five areas at once. Finances are tracked through management accounts, enrolment through admission numbers, but governance and operational efficiency tend to be blind spots. The light audit surfaces them. It is also worth noting that in the light audit, AI readiness is necessarily self-rated: what is captured is leadership's perception of where the school stands, not an evidence-informed picture drawn from policy documents, staff training records, or operational data. The deep audit addresses that gap.

What the light audit is good for:

• A quick health check when you want a general picture
• Identifying which dimensions might need deeper investigation
• Starting a conversation in SLT about institutional health
• Exploring IRIS5 before committing to anything
• Schools that are doing fine and just want confirmation

What the light audit can't do:

• Verify whether your perceptions match reality
• Analyse your actual documents and data
• Give you specific, metric-based findings
• Provide benchmarking against comparable schools
• Generate a report detailed enough for board presentation

The light audit is honest about what it is. It is perception-based. If your leadership team believes governance is strong, the light audit will reflect that. Whether governance actually is strong is a different question, and that is where the deep audit comes in.

The Deep Audit: Perception Meets Evidence

The deep audit does everything the light audit does, then adds a second layer. You upload documents, including financial statements, policies, enrolment data, governance records, and curriculum documents, and the system analyses them using AI. Then it compares what the documents say with what you said in the questionnaire.

That comparison is the most valuable part. We call it the perception-to-evidence gap, and it's where the real findings live.

Consider a school that completes the questionnaire and rates its financial sustainability as green: strong reserves, healthy operating surplus, no concerns. When the management accounts are analysed, the "healthy surplus" turns out to be almost entirely driven by a one-off property sale. Strip that out and the school is running a 3% operating deficit, with cash reserves covering 38 days of operations, well below the 90-day threshold most advisors would consider adequate.

The light audit would have shown green. The deep audit showed red. Same school, same leadership team, completely different picture.

What the deep audit gives you:

• Evidence-based RAG ratings cross-referenced against your perception
• Specific metrics pulled from your actual documents
• The perception-to-evidence gap for each dimension
• Benchmarking data where available
• A detailed report suitable for board review and strategic planning
• Prioritised findings with actionable recommendations

Side-by-Side Comparison

When to Use the Light Audit

You're just exploring. Maybe you've heard about IRIS5, or someone recommended a diagnostic tool, and you want to see what it's about before investing time. The light audit is the right entry point. No commitment, no cost, and you'll get a sense of whether a deeper look is warranted.

You want a quick pulse check. Things feel generally okay, but you haven't done a formal assessment in a while and you'd like to know if anything jumps out. The light audit will flag any dimension where your self-assessment raises concerns.

You're running a preliminary conversation with SLT. Before proposing a full audit to the leadership team, the light audit gives you something concrete to discuss. "We scored amber on governance and green everywhere else; do we want to look deeper at governance?" is a much better conversation than proposing an audit on instinct alone.

When to Use the Deep Audit

You're making strategic decisions. If you're planning a fee increase, considering a new campus, restructuring SLT, or changing your curriculum offer, you need evidence rather than hunches. The deep audit gives you the data to back up or challenge those plans.

You're preparing for accreditation. Bodies such as CIS, BSO, ISI, WASC, and NEASC assess governance, financial health, and operational quality as a core part of their frameworks, which are precisely the areas IRIS5 diagnoses. A school that has worked through its IRIS5 findings and addressed the issues they surface will be in a stronger position when an accreditation team arrives, because it has done the underlying work, not because it has rehearsed the process. A deep audit gives you the evidence base to understand where that work is needed. The deep audit is priced for single-school use, making it accessible without requiring a multi-school procurement budget.

You're reporting to the board. Boards want evidence. A light audit gives you opinions. A deep audit gives you documented findings with specific metrics. If your board is asking hard questions about institutional health, you need the deep version.

You're dealing with a specific concern. Enrolment has dropped for two consecutive years. Your operating surplus has been declining. Staff turnover is above average. When there's a known issue, the deep audit tells you whether it's isolated or symptomatic of something bigger.

Be Honest About What You Need

Every school could be told it needs a deep audit. It would be better for our bottom line, but it would not be true, and it would not be helpful.

If your school is in a stable position and you want to check there's nothing being missed, start with the light audit. It costs nothing and takes less time than a coffee meeting. If the results raise questions, moving to the deep version is a perfectly sensible path. One caution worth noting: if your light audit returns all-Green across the board, treat that as a prompt to test your assumptions rather than as proof there is nothing to find. All-Green from a perception-only instrument means leadership believes things are fine; it does not verify that they are.

If you are facing decisions that will shape the school for the next five years, or if there is a specific concern that needs investigating, go straight to the deep audit. The perception-to-evidence gap alone is worth it. Knowing whether what leadership believes about the school matches reality is the difference between good strategy and guesswork.

Either way, the result is a clearer picture than before. That is the point of any diagnostic: not to tell a school what to do, but to make sure decisions are made with eyes open.

Not Sure Which to Start With?

Answer these four questions to decide in under a minute:

1. Do you need a board-ready report with specific metrics? If yes, go to the deep audit. The light audit does not produce documentation at that level.
2. Is there a specific known concern, such as declining enrolment, a financial trend that's worrying, or a governance gap? If yes, go to the deep audit. Perception-only data will not tell you enough.
3. Are you exploring IRIS5 for the first time, or looking for a general pulse check before deciding whether to go deeper? If yes, start with the light audit.
4. Do you have 45 minutes and the relevant documents available right now? If yes and either of the first two questions also apply, go straight to the deep audit. If not, the light audit takes 20 minutes and you can upgrade later.
