What are the main differences between the QLTS and SQE?

In Autumn 2021, the SQE will replace the QLTS and will forever change how you qualify. After the SQE is introduced, the QLTS will no longer be available as a route to qualification as a solicitor. The introduction of the SQE is expected to drive up international applications to levels not seen in many years.
The purpose of the QLTS is to assess foreign qualified lawyers. The purpose of the SQE is similar, but the SQE will assess all aspiring solicitors, whether UK university law graduates, non-law graduates, apprentices, legal executives, paralegals, or foreign qualified lawyers, regardless of their background.
The overall structure of the SQE and QLTS assessments are similar in the way that they are both divided into two different sections and that the first section must be passed before the second can be attempted. The QLTS is structured into two different parts, Part 1, MCT, and Part 2, OSCE. SQE will also have two different parts in stages, SQE Stage 1, Functioning Legal Knowledge Assessments, and SQE Stage 2, Practical Legal Skills Assessments. As in the QLTS, SQE Stage 1 will be available at various international centres, but SQE Stage 2 will only be available in England and Wales initially.
