About the English proficiency test (C1)

The English Proficiency (C1) test assesses English communication skills at the C1 level of the Common European Framework of Reference for Languages (CEFR). The test rates candidates in grammar and vocabulary, sentence composition, reading comprehension, and listening comprehension, touching on four key areas:

  • Reading: The candidate’s ability to accurately comprehend complex, technical texts

  • Writing: How well an applicant creates structured and error-free writing

  • Speaking: The ability to convey thoughts and ideas verbally on any topic

  • Listening: Comprehension of spoken English, including various accents, idioms, and expressions.

Employees with C1 English language proficiency can clearly and effectively discuss ideas, plans, and goals with customers and colleagues. They can create well-structured reports, presentations, webinars, and other materials in English to help promote the company.

Using this English proficiency test for job applicants ensures your new hires can uphold high standards in external and internal communications. Effective communication in the workplace is crucial because 72% of leaders believe it contributes to employee productivity.

This English test for employment provides a bias-free approach to identifying top candidates with the language skills necessary to support your business’s growth. It also helps you open up your pipeline to nontraditional candidates who might have learned English via Duolingo and informal work experience rather than via expensive language courses and examinations (i.e., IELTS, Cambridge English exams, TOEFL IBT).

VP of engineering, mid-market (51-1000 FTE)

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

Why are English C1 skills important to employers?

Assessing English C1 communication skills is important to employers because it shows how potential employees can navigate advanced communication tasks, such as delivering detailed project updates, understanding complex instructions, and contributing to strategic discussions.

Using an English proficiency test for job applicants helps employers identify individuals with the language proficiency needed to thrive in professional environments. This is crucial for high-volume hiring and when recruiting remote workers from different parts of the world where English is a foreign language.

Confirming advanced language skills with an English C1 (Advanced) test can result in higher productivity, smoother collaboration, and a more cohesive remote work environment.

For instance, Click&Boat, a boat rental platform, uses test results from our English proficiency assessment tests when hiring new customer service agents. This strategy has helped the company hire top performers who are 30% more productive than the rest of the team.

What job roles can you hire with our English proficiency skills test?

Create a multi-measure assessment: 4 tests to pair with the English proficiency test (C1)

You can combine up to five different tests in an assessment for a more comprehensive candidate evaluation. This holistic approach helps you make more informed hiring decisions and ensures your new team members have the right level of English as well as the right skills, traits, and mindset.

Improve your hiring process by combining the English C1 (Advanced) test with these four complementary tests:

  • Communication Skills test: Measures a candidate’s ability to handle common workplace communication scenarios, including negotiation, conflict resolution, and team collaboration. This test ensures that your hires can effectively communicate across departments, build strong professional relationships, and maintain a positive work environment.

  • Culture Add test: Identifies how well an applicant aligns with your organization’s values and whether they can bring fresh perspectives that complement your team. This test ensures new hires can adapt to and enhance your existing company culture while contributing positively to the team’s success

  • Negotiation test: Gauge how a job seeker handles difficult discussions, influences others, and uses their persuasion skills. This test is particularly useful if you’re hiring salespeople, consultants, or other professionals who need to use their English language skills to communicate with clients and discuss sensitive issues like pricing.

  • Problem Solving test: Evaluate candidates’ ability to analyze complex information and use critical thinking in the decision-making process. Combining this test with the English C1 (Advanced) test ensures you hire people who aren’t just fluent speakers but also sharp thinkers.

Note: We haven’t included any role-specific skills tests here because they depend on the position you’re hiring for. However, we highly recommend you add at least one in your five-test assessment to ensure your candidates possess the right skills for the job.
