Letter of Application (FIRST)

Dear Sir / Madam,

Recently I saw your advertisement for activity leaders at your summer camps for children, and I would like to apply.

I am a 24-year-old Spanish student currently studying English at a college in Madrid. My college report describes me as motivated, enthusiastic, cheerful and confident. I believe these personal qualities would be very useful for the role of activity leader. Although I have no professional experience working with children, I have several young nephews and nieces who(m) I often take care of. I am also very active and play team sports such as volleyball and baseball.

I would like to work for you because I enjoy being with young people and am keen on sharing my enthusiasm for sports with them. The job would also give me an ideal opportunity to practise my English.

I believe I would be able to make a success of this job and I hope you will consider favourably my application.

Thank you for your time. I am looking forward to hearing from you.

Yours faithfully,
Carlos Álvarez

(On the streets 'who' would mostly be used but as this is a formal document, one should write 'whom'. It is also grammatically correct.)

I look forward to hearing from you. [Both versions are correct, but this is the standard phrase people use in applications]

** This sentence is correct, but it would be more positive if you phrased it like this:

"I have a great deal of informal childcare experience looking after several young nieces and nephews." (You should avoid the words 'no experience'!!)

Sounds good!
