| Sign of β | Description | |||
|---|---|---|---|---|

| + | 0 | + | 0 | Double positive selection. Positive and linear self-selection to teacher training with respect to both Matura score and early achievements at UW |
| − | − | + | + | Thriving specialists. Many teachers recruit themselves from among students who scored low on their Matura, but who perform very well within their UW programme. |
| − | 0 | 0 | 0 | Random selection from among low-profile students. The effect of Matura score on self-selection to teaching is linearly negative. Later experience at the university has no impact on students’ decisions |
| + | − | 0 | 0 | Middling skills selection. Teaching career is not attractive for low-performing students, but its attractiveness increases at a falling rate as we move along the achievements distribution. |
| 0/+ | 0 | + | − | Falling back students. Achievements on Matura do not affect students’ choices, but teaching is more likely to be chosen be those struggling academically while at UW |
| + | 0 | − | 0 | Mismatched. Prospective teachers had good scores on their Matura, but nevertheless they struggle at their university programme. |
| − | 0 | − | 0 | Double negative. Negative and linear self-selection to teacher training with respect to both Matura score and early achievements at UW |
