3  Meta

This chapter contains variables that provide meta-information about the data.

3.1 status

An indication of how complete the dataset is.

var_name status
var_stat_dyn dynamic
var_content_group meta
var_info_type aux
item_level_data is_no_scale
analysis_set_core FALSE
analysis_set_extended FALSE
values only_data = if there is at least one completed test;

only_meta = if there is a least one recorded grade; full = if there is at least one recorded grade and one completed test |

3.2 test_condition

Contains information about the conditions under which a test was conducted.

var_name status
var_stat_dyn test_condition
var_content_group meta
var_info_type aux
item_level_data is_no_scale
analysis_set_core FALSE
analysis_set_extended FALSE
values “supervised” = supervised by members of the LongGold-Team during testing at school; “unsupervised” = not supervised by members of the LongGold-Team; testing took place during Covid-19 pandemic, partly at home, partly at school under supervision of teachers

3.3 num_test_waves_p_id

This variable indicates the number of test waves, including incomplete test waves. Note: the count is determined before parts of the datasets of retained students are removed. Therefore, there may still be 7 measurement points (MZP), even though this is not possible.

var_name status
