The 2023 Tech Ed Study aimed to continue evaluating the success of ongoing technical education reforms in England, which aim to deliver high-quality learning experiences and support progression into desirable outcomes. The 2023 Tech Ed Study followed up with the second cohort of T Level learners in a second wave of longitudinal data collection, to understand learners' views and experiences in relation to the final year of their programmes. These learners will be followed up again in a third wave of data collection in the academic year after they have completed their course. To enable comparison between the second T Level cohort and learners enrolled on comparative courses, a sample of A level learners (all courses) and level 3 technical learners studying in the same technical routes as those offered for T Level were also surveyed about their experiences, reflections and short-term outcomes. In addition, the 2023 Tech Ed Study surveyed the third cohort of T Level Transition Programme (TLTP) learners at the end of their programme to capture experiences as the programme expands and develops. Finally, learners on Level 4 and 5 programmes were surveyed in the 2023 Tech Ed Study to understand learners' experiences on the post-reform programmes. Findings from this group, and future cohorts, will provide comparisons to the experiences provided by the pre-reform cohort in the 2022 Tech Ed Study report. Findings in this report cover the surveys of all five learner groups, discussed in three separate chapters. The second T Level cohort is discussed alongside the comparator A level and other Level 3 technical learner groups. The TLTP and level 4 and 5 learner groups are discussed in separate chapters, with references made to findings from previous reports to allow for comparisons of learners' experiences across cohorts.
