PTE (Pearson Test of English) is a computer-based English language proficiency test that measures the ability of non-native English speakers to communicate effectively in academic and professional settings. The PTE test assesses four language skills - listening, reading, writing, and speaking - and is designed to provide an accurate and reliable measure of a candidate's English language proficiency. The PTE test is available in two formats:

1. PTE Academic: designed for individuals who wish to study at the undergraduate or postgraduate level in an English-speaking country.
2. PTE General: designed for individuals who wish to work or train in an English-speaking country or emigrate to an English-speaking country.

Both formats of the PTE test are computer-based and scored by an automated system, with results available within 48 hours of completing the test. The test duration ranges from 2 hours to 3 hours, depending on the format and the specific requirements of the institution or organization that requires the test. The PTE is widely recognized and accepted by universities, employers, immigration authorities, and other professional organizations worldwide as a valid measure of English language proficiency.
