The International English Language Testing System (IELTS) is designed to measure English proficiency for educational, vocational and immigration purposes. The IELTS measures an individual's ability to communicate in English across four areas of language: listening, reading, writing and speaking. The IELTS is administered jointly by the British Council, IDP: IELTS Australia and Cambridge English Language Assessment at over 1,100 test centres and 140 countries. These test centres supervise the local administration of the test and recruit, train and monitor IELTS examiners.

IELTS tests are available on 48 fixed dates each year, usually Saturdays and sometimes Thursdays, and may be offered up to four times a month at any test centre, including Philadelphia depending on local needs. Go to IELTS test locations to find a test centre in or nearby Philadelphia and to check for upcoming test dates at your test centre.

Test results are available online 13 days after your test date. You can either receive your Test Report Form by post or collect it from the Test Centre. You will normally only receive one copy of the Test Report Form, though you may ask for a second copy if you are applying to the UK or Canada for immigration purposes - be sure to specify this when you register for IELTS. You may ask for up to 5 copies of your Test Report Form to be sent directly to other organisations, such as universities.

There are no restrictions on re-sitting the IELTS. However, you would need to allow sufficient time to complete the registration procedures again and find a suitable test date.
