T Levels are a type of technical-based qualification in England that are designed to meet the needs of industry and prepare students for work, further training, or study. They are two-year courses that can be studied by 16-18 year olds after finishing their GCSEs and are based on the same standards as apprenticeships, designed by employers and approved by the Institute for Apprenticeships and Technical Education. T Levels are the responsibility of the Minister of State for Skills, Apprenticeships and Higher Education in the Department for Education.

T Levels are a Level 3 qualification on the Regulated Qualifications Framework and require students to undertake both a technical qualification and an industry placement with an employer. Students can expect to gain a broad knowledge, with skills and behaviors necessary for employment in an occupation or industry related to their field of study, an opportunity to develop specialist technical skills relevant to at least one occupation, and the relevant English, Maths, Science, and Digital skills.

T Levels are an alternative to A levels, apprenticeships, and other 16 to 19 courses and are equivalent in size to 3 A levels. They focus on vocational skills and can help students gain the skills that employers need. T Level students spend 80% of the course in their learning environment, gaining practical and knowledge-based learning at a school or college, and the other 20% is a meaningful industry placement, where they put these skills into action.

In contrast, testosterone levels, often abbreviated as T levels, refer to the amount of testosterone hormone found in men and, to a lesser extent, in women. Testosterone is a hormone that plays a crucial role in the development of male reproductive tissues and promotes secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. Low T levels in men can lead to a range of physical and mental health problems, including decreased sex drive, erectile dysfunction, depression, and fatigue. Testosterone therapy may be prescribed for men with low T levels, but it carries some side effects such as oily skin, fluid retention, and testicles shrinking.
