Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
Data collection on student and researchers (and other categories) is based on Article 38 of Directive (EU) 2016/801 on the conditions of entry and residence of third-country nationals in the framework of an intra-corporate transfer.
The following datasets are collected under this framework:
Authorisations for study and research by reason, type of decision, citizenship and length of validity (migr_ressrath)
Authorisations for long-term mobility of researchers by reason, type of decision, citizenship and length of validity (migr_ressrltm)
Notifications for research and study by reason, decision, citizenship and length of validity (migr_ressrntf)
Directive (EU) 2016/801 was transposed at national level on 11 May 2018, legislative decree n. 71.

11.1. Quality assurance
Continuous quality assessments of data retrievals by the Italian Ministry of the Interior and the National Institute for Statistics (ISTAT). Quality evaluation cycle between the Italian Ministry of the Interior and National Institute for Statistics (ISTAT) on the annual data exchange.
11.2. Quality management - assessment
Data is of good quality as it is taken from entries in the Italian "Stranieri web platform" and "SPI 2.0 platform", which documents each case in Italy. A unique code or biometric data allows for the linkage of data within the SDI-database. Upon processing of national statistics, general plausibility checks are performed. Some data is also checked at random during the reference year, in order to assess data quality. Any inconsistencies are reported to the competent authorities.
12.1. Relevance - User Needs
The SR statistics produced are regularly used by national administrations: academic researchers and civil society groups working on a wide range of topics including the integration of immigrants, the development and monitoring of national asylum and immigration procedures, and the projection of the future population and labour force.
European and international level
The main users of SP statistics are Eurostat and EU Commission. The statistics are used in several publications of the Commission, as well as in the preparation of regular reports, policy proposals and analysis. The statistics also provide an input to the EMN studies and reports that address specific issues of current policy importance.
12.2. Relevance - User Satisfaction

See table 12.3. in annex ‘Quality report tables on student and researchers’.
12.3.1. Data completeness - rate
Not applicable.

Overall high accuracy: The reported statistics measure accurately the target population because the database includes all cases. Some cases that are entered into the database after data are retrieved for the data submission to Eurostat and therefore missing, which amounts to an underestimation of about 0.1-0.5% in total.
