Science Advances Under Evaluation: What the Status Usually Means

Science Advances does not use a deeply transparent author-facing status system. The journal relies on a handling-editor model, and the visible status language collapses several internal steps into one broad label.

That is why authors get stuck trying to decode a phrase that the system was never designed to decode precisely.

What Under Evaluation most often covers:

1. assignment to a handling editor
2. editorial read for fit and significance
3. reviewer selection and invitation
4. active reviewer consideration in some cases

This matters because authors often ask the wrong question: "What exactly does this status mean right now?"

The better question is:

Given the amount of time that has passed, what phase am I most likely in?

Before getting lost in portal semantics, use the timing around the status as your main interpretive tool.

Use elapsed time, not the wording alone.

This is not a mechanical rule, but it is much better than overreading the label itself.

Science Advances uses academic editors rather than a purely in-house editorial model. That changes the feel of the process.

The manuscript may be moving more slowly than at journals with full-time in-house editors because the handling editor is also an active researcher. That means:

• triage can be slower
• reviewer recruitment can take longer
• interdisciplinary papers may need extra matching effort

The upside is that the manuscript is often being read by someone scientifically close to the problem. The downside is that timing is less uniform.

During Under Evaluation, the editor is usually deciding some combination of:

• whether the paper has broad enough interest for Science Advances
• whether the claims are strong enough relative to the journal's bar
• whether the scope is too narrow for the venue
• which reviewers could credibly assess the paper

That is why the waiting period can feel opaque. A lot is happening, but not much of it is reflected in the author-facing status language.

Not automatically.

This is one of the biggest author misconceptions. Some journals use distinct labels that let you infer movement into external review. Science Advances is not especially generous with that visibility. A paper can still be under editor-side evaluation for a while before a desk rejection arrives.

That said, timing still helps:

• a very early rejection is more likely to be a desk decision
• a longer stay in Under Evaluation with no rejection increasingly suggests the manuscript is under deeper consideration

So the honest answer is:

No, the status alone does not prove you passed the desk. But extended time without rejection usually improves the odds that you are beyond the first editorial filter.

Most of the time, a long wait is not a coded editorial message. It is a process problem.

Common reasons:

• reviewers decline and need replacement
• the topic is interdisciplinary and hard to staff properly
• the handling editor is balancing the manuscript with normal faculty workload
• one reviewer is late and the editor is waiting rather than deciding with partial input

Authors often assume that a long wait means the editor hates the paper. In practice, slow review more often means the system is struggling to complete the process cleanly.

This is where authors often need the clearest rule.

You should generally not follow up during the early waiting period unless there is some obvious technical problem or submission-system error.

A follow-up becomes more reasonable when:

• the paper has remained in Under Evaluation well beyond the journal's usual first-decision window
• you have already allowed a fair cushion for reviewer delays
• there has been no other communication from the journal

The purpose of the email is not to pressure the editor. It is to confirm whether the manuscript is still moving and whether there is a known delay.

A good follow-up email is short:

I am writing to ask whether there are any timing updates on manuscript [ID], which has been under evaluation for [time period]. We understand the review process can take time and would appreciate any guidance you can share.

That is enough. Do not write a long justification, and do not email repeatedly.

Do not withdraw prematurely

If the manuscript is still plausibly moving through reviewer handling, a withdrawal can waste a real chance at a strong outcome.

Do not assume silence means rejection

At Science Advances, silence often means exactly what it looks like: a slow editorial system doing slow editorial-system things.

Do not obsess over micro-status interpretation

The system is not giving you a hidden code to solve. Most of the useful interpretation comes from elapsed time and context, not from trying to reverse-engineer a single label.

The right mindset is not "What secret message is the journal sending me?" It is:

• Are we still within a normal waiting band?
• Are we now far enough past the normal window that a polite inquiry makes sense?
• If the paper is rejected, do we already know our next-best path?

This keeps the status in proportion. It matters because it reflects process movement. It should not dominate your week.
