Prof., Dokuz Eylül Universty, Turkey, [suat.turkoguz@gmail.com](suat.turkoguz@gmail.com)  \nThis study aimed to investigate the item Response Time Fidelity scores (RTFs), KuderRichardson Reliability (KR20) and Cronbach’s Alpha Reliability (α) coefficients, calculate KR20 coefficients with RTFs for 30 threshold points between 1 and 30 seconds and compare these values on plots, estimate the threshold point in the literature to support these plots and conduct risk analyses with Cox Proportional Hazards Model (Cox-HM) on the initial data and the new data determined by the threshold value. This study is a descriptive research. The participants were pre-service science teachers at a state university in Turkey (n:115) . The study was conducted in two groups. In Group-1 (n:57), a Three-Tier Diagnostic Test (3TDT) was performed, and in Group-2 (n:58), a Multiple-Choice Test (MCT) was applied. Tests consisted of 63 items and chemical concepts. As a result, it was found that item response times could be used in the validity and reliability studies of measurement tools. Moreover, examinees spent less time and effort in Tier-II of 3TDT. In future research, response times and RTFs may have roles in development of 3TDTs about different concepts. Moreover, these may be used in Rasch and Parametric Logistic Analysis for 3TDT. This study may be repeated using different psychometric scales.  \nKeywords: tier-diagnostic, threshold, reliability, cox-hm, chemistry  \nINTRODUCTION  \nMeasurement and assessment tools are used to determine the degree of realization of pre-determined learning objectives and outcomes as a result of the teaching process. Multiple-Choice Tests (MCTs) and open-ended questions are widely used testing and assessment tools. With these tests, information about the learning process cannot be determined while measuring the knowledge levels of the students as a result of the teaching process (Akınoğlu, 2011) . Therefore, it will be beneficial to make measurement and assessment based on the process, rather than result-oriented measurement and assessment (Bektaş & Kudubeş, 2014) . In addition to measuring how many questions students answered correctly in an examination, we need to know how much they have learned. MCTs and open-ended test have advantages and disadvantages. Tier Diagnostic Tests (TDTs), which are thought to overcome the disadvantageous aspects of these tests, have become widespread. Below, the causes and justifications of the advantageous and disadvantaged aspects of MCT and TDT are listed respectively.  \nThe reasons for the popular preference of MCTs are that they can be applied to a large number of people and it is easy to prepare and assess. As known, MCTs consist of questions and options one which is the correct one, while the others are distracters. However, these tests do not provide an idea ofwhy the examinee has chosen that option. The lack of reasons for choosing the options oftest items may constitute a problem in terms of understanding the ways in which concepts are constructed. Furthermore, it may prevent the determination of the student’s misconceptions. MCTs are fast in terms  \nCitation: Türkoguz, S. (2020) .
