Research aims and objectives
Aims and objectives work as a pair: the aim is the broad goal of your research, while the objectives are the specific, achievable steps that get you there.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Aims: the broad goal
The aim is the destination — a single, concise statement of what your research as a whole sets out to achieve. It is deliberately broad and is usually phrased with an open verb such as "to investigate", "to explore", "to evaluate" or "to understand". Most dissertations have just one overarching aim, occasionally two, that captures the purpose of the entire project in a sentence. Because it is general, an aim is not directly measurable on its own; it sets the direction that the more concrete objectives then make achievable. A clear aim keeps the whole study focused on a single, coherent purpose.
Objectives: the specific steps
Objectives are the route to the aim — the specific, concrete tasks that, completed in sequence, deliver it. Where an aim is broad, each objective is narrow, action-oriented and measurable, written with precise verbs such as "to identify", "to measure", "to compare" or "to analyse". A study typically has three to five objectives, each a step the reader can see being accomplished in the work. Together they should add up to exactly the aim — no more, no less. Well-written objectives also map onto the structure of the dissertation, giving each chapter a clear job to do.
Writing objectives with SMART criteria
A useful test for objectives is the SMART framework: each should be Specific (clearly defined), Measurable (you can tell when it is met), Achievable (feasible with your time and resources), Relevant (it genuinely serves the aim), and Time-bound (completable within the project). SMART criteria turn vague intentions into checkable commitments and expose objectives that are too broad or unrealistic. Avoid objectives that merely restate the aim in different words, and avoid so many that the project becomes unmanageable. Three to five sharp, SMART objectives are usually stronger than a long, loose list.
Keeping aims and objectives aligned
Aims and objectives must hang together. Read collectively, the objectives should fully achieve the aim and nothing beyond it — if an objective does not serve the aim, it does not belong; if the aim demands something no objective covers, an objective is missing. This alignment also threads through to the research questions, the methods and the conclusion, which should answer back to the same aim and objectives. Checking this alignment at the proposal stage prevents scope creep later. For the broader conceptual distinction between aims and objectives, see CASRAI’s comparison page.
Key facts
At a glance
- Aim: the broad, overarching goal of the research
- Objectives: the specific, measurable steps that achieve the aim
- Number: usually one aim and around three to five objectives
- Aim verbs: broad — "to investigate", "to explore", "to evaluate"
- Objective verbs: concrete — "to identify", "to measure", "to compare"
- Test: write objectives to be SMART; together they must equal the aim
Common questions
FAQ
What is the difference between an aim and an objective?+
An aim is the broad, overall goal of your research — what you ultimately want to achieve — while objectives are the specific, measurable steps that get you there. A study usually has one aim and several objectives. The aim says where you are going; the objectives say how you will travel. Together, the objectives should fully accomplish the aim.
How many objectives should a dissertation have?+
Typically three to five. Too few may not cover the aim; too many make the project unwieldy and hard to complete. Each objective should be a distinct, necessary step toward the aim, and collectively they should add up to it exactly. Quality and alignment matter more than number — a handful of sharp objectives beats a long, vague list.
Should objectives be SMART?+
It is a helpful discipline. Making each objective Specific, Measurable, Achievable, Relevant and Time-bound turns loose intentions into checkable commitments and reveals any that are too broad or unrealistic. Not every discipline insists on the SMART label, but objectives that are concrete, measurable and feasible are stronger and easier to deliver than vague ones, whatever you call the test.
