What a conclusion should do
The conclusion is the final impression your work leaves on the reader, and the marker. A strong conclusion demonstrates that your argument has progressed logically across the essay or dissertation, and that the central question has been genuinely addressed rather than simply discussed. A weak conclusion merely lists what was covered in the body, leaving the reader without a clear sense of what was established.
The conclusion typically constitutes approximately ten per cent of the total word count. If you need support with essay or dissertation writing, GradeQuill's essay writing service and dissertation editing service are available at all academic levels.
Synthesise, do not summarise
The most important distinction in conclusion writing is between summarising and synthesising. Summarising means restating what each section covered, "in the first section, this essay discussed… in the second section, it examined…". Synthesising means drawing the threads of your argument together to show what they collectively mean.
A synthesising conclusion might look like: "The evidence examined in this essay collectively suggests that leadership effectiveness in organisational change is not an independent variable but is contingent upon cultural context, a position supported by both the theoretical frameworks discussed and the empirical evidence reviewed." This is not a list of what was covered; it is a statement of what was established.
Return to your thesis
A strong conclusion circles back to the thesis statement introduced in the introduction, demonstrating that the promise made at the outset has been fulfilled. This does not mean repeating the thesis word for word, it means showing how the argument developed across the essay has addressed the central question.
If your introduction argued that "social media use has a predominantly negative effect on student academic performance", your conclusion should reflect on the extent to which the evidence reviewed supports, complicates, or qualifies that position, not simply reassert it.

Address broader implications
The conclusion is also an opportunity to consider the broader significance of your argument. What do your findings mean for theory, practice, or policy? If you are writing a dissertation, what contributions does your research make to the existing literature? If you are writing an essay, what are the implications of your argument beyond the specific question set?
This does not need to be extensive, a sentence or two drawing out the wider significance of your argument demonstrates intellectual engagement that goes beyond the immediate task.
Acknowledge limitations
In dissertation conclusions particularly, it is appropriate to briefly acknowledge the limitations of your analysis. This might include the scope of sources reviewed, the constraints of the methodology, or the particular context to which your findings apply. Honest acknowledgement of limitations demonstrates critical awareness and does not undermine your argument.
Where appropriate, suggest directions for future research, questions that your analysis has raised but not answered, or areas that would benefit from further investigation.
What to avoid in a conclusion
Several common mistakes weaken conclusions significantly. Do not introduce new evidence, new arguments, or new sources, the conclusion is a space for reflection and synthesis, not expansion. Do not begin with "in conclusion" or "to summarise", these phrases are redundant and add nothing. Do not simply list the contents of each section. Do not end with a vague or grandiose statement disconnected from the specific argument of your essay.
