National Cohort Research Education with pupils belonging to cohort JJJJ in primary education (from 01-09-2010)

National Cohort Research Education (NCO) The NCO microdata files were compiled by the Central Bureau of Statistics (CBS) for the National Cohort Research Education (NCO). The NCO has been initiated and is funded by the National Educational Research Agency (NRO). For these files, existing register data from the social-statistical files (SSB) of CBS and existing educational records of the Education Basic Register (BRON) of the Education Implementation Service (DUO) have been combined. The files are intended as a backbone and contain only the torque key (RINPERSOON and RINPERSOONS) and the school year in which the pupil entered the cohort. The year in the file name refers to the relevant school year YYYY/YYYY+ 1.

Students appear in multiple cohorts if they have remained seated or if they accelerated. In some cases, students appear to be slowing down. For example, there are some students who are in group 8 in 2010 and in 2011 in group 2. These are probably administrative errors. This has not been corrected. If they stay in group 1, the starting year in both cohorts is equal to the selected cohort. In all other situations, in the cohort in which they started, the starting year corresponds to the cohort year, and that they have a later start year in the cohort in which they enter. Based on the start year, the pupils who were originally started in the respective cohort can be selected. Because the side-influencers are also included, by linking with the educational characteristics, a cross-section of all pupils in a certain grade and school year can be given. ### Population These files contain data of the pupils who are in the first year of primary education in a given school year, supplemented each year with the side-influencers.国家队列研究教育项目（National Cohort Research Education，简称NCO） NCO微数据文件由荷兰中央统计局（Central Bureau of Statistics，简称CBS）为国家队列研究教育项目（NCO）编制。该项目由国家教育研究机构（National Educational Research Agency，简称NRO）发起并资助。本数据集整合了CBS社会统计档案（social-statistical files，简称SSB）的现有登记数据，以及教育执行服务机构（Education Implementation Service，简称DUO）的教育基础登记册（Education Basic Register，简称BRON）现有教育记录。 本数据集旨在作为核心研究框架，仅包含个人识别密钥（RINPERSOON与RINPERSOONS）以及学生加入队列的学年信息。文件名中的年份指代对应学年YYYY/YYYY+1。 更多数据获取详情请参见： > https://www.cbs.nl/nl-nl/onze-diensten/maatwerk-en-microdata/microdata-zelf-onderzoek-doen ### 方法论 本数据集旨在作为核心研究框架，仅包含个人识别密钥（RINPERSOON与RINPERSOONS）以及学生加入队列的学年信息。若学生留级或跳级，则会出现在多个队列中；部分学生或存在降级情况，例如部分学生2010年就读于八年级，2011年却就读于二年级，此类情况大概率为行政录入错误，且未被修正。若学生停留在一年级，则两个队列的起始年份与所选队列的起始年份一致；其余场景下，学生所在的起始队列的起始年份与队列年份相符，而其进入其他队列的起始年份则晚于该队列年份。 基于起始年份，可筛选出最初加入对应队列的学生。由于同时纳入了后续转入学生，结合教育特征进行关联后，即可获取特定年级与学年的全体学生截面数据。 ### 研究对象 本数据集包含特定学年小学一年级学生的相关数据，并每年补充后续转入的学生信息。
