Your essay should be written in your own words. Your ideas will be formed using perspectives, arguments, research, data etc. from your reading, and you must acknowledge this by using referencing. However, your writing should not be a series of paraphrases from other people's writing.
Perfect introduction for an essay
Your introduction should tell the reader what to expect from your essay. Stay focused on the question, and keep it brief. Do not give very broad background information on the general topic, but focus instead on what is relevant to answering the set question.
What should be in a introduction of an essay
There are no absolute rules about this but, as a general guide, it should be between 5-10% of your whole essay. The amount of detail that you can include in your introduction therefore will differ, depending on your word count. Even in a short essay you should still cover the main points outlined above. Here is an example of a shorter introduction on the same topic. This shorter version shows that the same points can be covered in a more concise way. Both versions are well executed but written in different styles and for essays with different word limits.
On writing the college application essay
Concern about racism in the police has increased since the 1980's, following a number of high-profile cases that highlighted that ethnic minorities did not receive treatment equivalent to their white counterparts. The focus of this concern has been whether racism operates at the individual level or whether it is embedded in the policies and practices of the police (Easton and Piper, 2005). Two significant inquiries, carried out in the intervening period, the Scarman report and the Macpherson report, will provide a focus by which to critically analyse the concept of institutional racism in policing and evaluate the policy responses to it. Whist some progress has been made since these two inquiries were carried out, many improvements still need to be made to overcome institutional racism.
