GLH (Guided Learning Hours) and TQT (Total Qualification Time) are terms commonly used in vocational qualifications to help define the amount of time a learner is expected to spend on heir studies.
1. GLH (Guided Learning Hours)
GLH refers to the number of hours a learner spends being directly taught, supervised, or supported during their course. This includes the time spent in activities such as:
- Classroom instruction
- Practical workshops
- One-on-one tutoring or mentoring sessions
- Online learning sessions with tutor support
In other words, GLH represents the time that learners are actively engaged with their instructors or learning activities.
2. TQT (Total Qualification Time)
TQT represents the total amount of time a learner is expected to invest in completing a qualification, including:
- GLH (Guided Learning Hours): Time spent on direct learning, as explained above.
- Self-Directed Learning: This includes time spent on independent study, research, assignment completion, preparation for exams, and any other work the learner does outside of direct teaching hours.
TQT is a broader measure that includes all the time required to achieve the qualification. It helps learners and employers understand the overall commitment required for the qualification.
Key Differences Between GLH and TQT:
- GLH focuses on direct learning with guidance or supervision.
- TQT includes GLH as well as independent study time and other learning-related activities.
Example:
If a qualification has a TQT of 600 hours and a GLH of 250 hours, it means the learner should spend 250 hours in direct learning (classroom, online, or tutor-led sessions) and 350 hours on independent study or research.
