The PhD Salary Ladder is yearly negotiated and currently has several steps than can be seen updated at KTH website
Step 1 is the initial salary. Advancement to step 2, 3 and 4 is done after achieving the sub targets which are defined in the Individual Study Plan (ISP) corresponding 30 %, 50 % and 80 % of the total degree requirements of a doctoral diploma. Deviations from the schedule in the ISP must be motivated in writing by the main supervisor in consultation with the Director of Third Cycle Education. In absence of explicit and objective sub targets advancement in the doctoral ladder is done after 30 %, 50 % and 80 % of the time plan for the studies.
What is written in the ISP governs if a PhD candidate advances up the salary ladder. See more information about ISP in the menu to the left.
The PhD Chapter has compiled an evaluation model that can be looked upon as support when estimating how much progress a PhD Candidate has made. Note, this is not an official model, merely a recommendation from the chapter. It can be found here: PhD Ladder Progress Evaluation Model.
