Abstract
We look at data acquired during the 2020 applications cycle to Master's programs in Psychology in Israel. The data is obtained from the matching system that governs the market (the Israeli Psychology Master's Match, or IPMM). Starting from 2020, rank-order lists (ROL) were collected both before and after the interviewing period, and we can look at the evolution of preference between these two periods. We show a correlation between being ranked highly by a program and increasing its rank compared to the previously inputted rank. We also link these results with the applicants' responses to a post-match survey regarding their motivation to change their preferences because of the interviews.

Experimental Design

Experimental Design
Applicants were asked to submit pre-interviewing ROLs that will be used in case they do not input their ROLs during the ranking period (it was made clear to applicants that this is a common phenomenon, and that starting from 2020 they are required to input "default ROLs" until April 19). It was confirmed with the participating institutions that no interviews were conducted prior to April 19. During the regular ranking period (June 7 to June 21) applicants will input their final ROLs. Applicants will actively submit their final ROL. This data, together with programs' ROLs will be provided to the researchers by the IPMM. In addition, the researchers will run a survey through the IPMM website.

It was confirmed with the participating institutions that no interviews were conducted prior to April 19. During the regular ranking period (June 7 to June 21) applicants will input their final ROLs. Half of those that previously reported their default ROLs would be presented with their default ROLs, and half would not be presented with them. In both cases, the applicants will actively submit their final ROL. This data, together with programs' ROLs will be provided to the researchers by the IPMM. In addition, the researchers will run a survey through the IPMM website.
