Abstract:
The purpose of the present report was to assess congruence between a language-based national examination (termed English placement test - EPT) and the Common European Framework of Reference for Languages (CEFR) levels. To this end, a series of methodological steps were put forth to accumulate evidence suggesting that language performance based on the EPT instrument can be split onto meaningful subgroups based on theoretical (expert judgement on difficulty level and CEFR correspondence) and empirical considerations (i.e., how well these levels and subgroups emerged). Participants were 2642 high school graduates who took on the EPT instrument as part of their entry criteria to the university and for the purposes of the present study only the structure subscale is presented. Items were classified as reflecting specific CEFR levels and a person-based analysis attempted to classify individuals sharing the same behavioral patterns. Results using a latent class analysis (LCA) indicated that a Pre-A1, an A1 an A2 a B1 and a B2 levels were present with regard to the structure domain of language. Results showed a strong alignment between the EPT structure domain and CEFR guidelines using various methodological approaches.

Ratio Level of Measurement
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated....
Differential Leveling
Interval Level of Measurement
Data measured using the interval scale are similar to ordinal level data because they have a definite arrangement. However, in the interval level of measurement, the differences between data values are meaningful even though the data does not have a starting point.

Ordinal Level of Measurement
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...
Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
