Living in Alberta, you will be immersed in an English environment which will provide multiple opportunities to hone your skills in that language.

It would be useful to assess your English proficiency when you arrive in Alberta. In Edmonton, Catholic Social Services can evaluate your skills through an exam called the Canadian Language Benchmarks Assessment (CLBA). This assessment is based on Canadian Language Benchmarks recognized across the country and allows you to enroll in an ESL course (English as a Second Language) corresponding to your skill level.

You can also complete a self-evaluation on-line on the following website:

The TOEFL (Test of English as a Foreign Language) is also an English-language test. Unlike CLBA, the TOEFL is based on international standards and is recognized around the world. Since it measures the level of listening and reading proficiency in English at a university level, its purpose is also different. It is often required to apply for admission at post-secondary educational institutions or to obtain a professional license. To assess your speaking abilities, some associations require that you pass the Language Proficiency Test offered by ESL educational institutions, in addition to the TOEFL.
