Help / Frequently Asked Questions (FAQ)
- Search terms that contain fewer than three letters are not considered.
- No distinction is made between capital and small letters. When entering "schule", you will also find matches for "Schule".
- Umlaut and ß: are not dissolved. By entering "Lehrkraefte", you will not find "Lehrkräfte", "Massnahme" F(measure) will not retrieve "Maßnahme". Umlaut and the respective vowel are treated equally (e.g. "Lehrkraft" finds "Lehrkräfte").
- Truncating: Search terms are automatically truncated – at the beginning and at the end of a word. Therefore, the delivered matches will contain an exact spelling of the search term, a plural, a flection or part of a word. Entry of "Maßnahme" will display "Unterstützungsmaßnahme" but also "Maßnahme zur" or "Maßnahmen". You can therefore also use incomplete terms for your search if you wish to abbreviate search terms or vary your search respectively if you are unaware of the exact term.
- Phrases: You can run a search for an exact string of letters or an exact combination of terms by using "quotation marks" for the search term. For example, "Teamarbeit im Unterricht" will only display records with an exact match of the string "Teamarbeit im Unterricht" (teamwork in lessons). On the other hand, if you enter the terms "Teamarbeit im Unterricht" without quotation marks, all the records will be displayed that contain either "teamarbeit" or "unterricht".
- You can use the simple search option to enter one or more terms in the field. Please use a blank space to separate several search terms.
- Conjunction of search terms: Several search terms are automatically linked with OR, delivered results will contain at least one of the search terms (e.g. "student participation" will deliver records that either contain the term "student" or the term "participation").
- The following contents are searched for simple search queries: title of study, scale or construct.
- The query is triggered by clicking onto the Search button or pressing the Return key.
- You can use the advanced search option to run a more precise search, permitting the use of specific search fields or limiting the search (e.g. regarding the year, number of items, alpha factor).
- You can choose from the following search fields respectively search options:
- Search on level: You can thus limit the search to scales or studies. The other fields are linked to this limitation, which can or cannot be used depending on the selection. The setting "all" means that scales and studies will be searched that match your query.
- Title: Searches in titles of studies and/or scales.
- Person: Search for persons involved in a study. Please use the surname of the relevant person.
- Institution: Limits search to an institution involved in the study, e.g. "DIPF".
- Construct: Exact search for scales allocated to a construct - in the original allocation of the study or pursuant to systematized DaQS construct scheme.
- Item-Text: Search in the full text of assessed items.
- Abstract: Refers to existing abstract of documented study, please note that such a description is not available for all the assessed studies.
- Target group: Enables targeted search for scales that can be used by a specific group of people.
- Number of items (min/max): You can determine how many items a scale should contain. You can either delimit a range of items or select a maximum respectively minimum number. Excluded items are not considered.
- Alpha factor of scale: Search can be delimited to scales with a certain validity score.
- Year (from/until): Can be used for searching studies that were published at a certain time or within a certain period of time.
- If you limit the search to either studies or scales, only the relevant fields will be available. The remaining search options will be inactive (shaded grey).
- Linking search terms: In the advanced search option, you can use one or several terms in a field. Please insert blank spaces between search terms. You can choose how the search terms should be linked. If you have selected all words (ticked box), all the terms will be found in the record. If the selection is deactivated and the box not ticked, at least one of the terms will appear in the matching record.
List of results
- Records matching your search are displayed in a compact overview of results, including relevant information sorted by scales and studies.
- You can find details regarding individual records by selecting one or more of the matching records in the list - i.e. ticking the respective boxes and clicking onto "display/ show". For scales. Alternatively, you can click onto a record (scales and studies).
- You can store information from the database locally on your computer. A transfer functionality is offered for the display of details, allowing download of all available information at a glance.
- Currently, contents are provided in ODT (OpenDocument Text) export format. The respective files can be further processed in MS Office Word (from Version onwards 2007 without, in older versions with additional plugin) and Open Office.
Browsing (thematic access)
- Alternatively to a targeted search, DaQS offers a general thematic search entry point to accessing the assessed scales in terms of a systematic catalogue. A construct scheme was especially developed for this purpose, drawing on constructs for school and instructional quality that are presented in a semantic context. We have categorised all of the scales assessed in DaQS into this construct scheme. You can either use the scheme in its graphical design or as a list for browsing. A brief theoretical description is provided for all the constructs in the scheme. Based on this overview, you can query a delivery of all the scales assigned to a particular construct.
- Construct scheme: Displays the systematic catalogue of the database at a glance and visualises allocation of constructs to categories and correlations between superordinate and pertinent specific constructs.
- Construct list: Displays all constructs used in the database system as a list. The categorisation of constructs according to the scheme was thus realised.
- Moreover, the list of studies presents an overview of all the studies assessed in the database.

Who can use the DaQS services?
- Primarily, the Database for School Quality targets quantitative empirical educational research. We address scientists from research and teaching, students and practitioners (e.g. staff working at the state institutes for quality assurance).
- Of course, the database is open to anyone interested in research on school and instructional quality.
What services does DaQS offer?
- Digital documentation of research projects respectively studies and their instruments in terms of descriptive outline data, processed assessment instruments and insights into questionnaires. DaQS is based on scales manuals, study profile sheets, original questionnaires and information submitted by responsible parties.
- Comprehensive search opportunities: "Quick and Dirty" by simple search for scales and studies or opting for a detailed search strategy in the advanced search. You can search at the scales, study and item level.
- Transfer of records that can be used locally.
- Systematisation of assessment instruments according to a specially developed DaQS construct system by retaining allocation from the original study.
What contents are provided?
- Outline data of studies.
- Assessment instruments including information on statistical parameters and source references.
- Original questionnaires in full text format.
- References (if available, link to full text).
- Construct categorisation including theoretical introduction.
- Principally, the database is accessible by any internet user, it is provided online by the German Education Portal
Does the use of DaQS involve any fees?
- No, the database can be used free of charge. However, we cannot guarantee that any external services users might access via a link from DaQS will be usable free of charge.
Can I reuse contents from the database? What do I need to know in this regard?
- You can principally use the contents from the database for private purposes. Please note however, that copyright legislation (UrhG) applies.
- When using contents accessible from DaQS, it is absolutely necessary to respect the rights of the copyright holder. In any case, contents should be cited properly by referencing the source and its copyright holder. This is not only determined by copyright legislation but also suggested by the principles of assuring good science practices.
How can my own study be indexed in DaQS? How can my study become accessible to the research community via DaQS?
- If you would like to make your research visible to the research community via DaQS and thus provide a central access point for the assessment instruments you have developed, you are welcome to contact us (daqs[at]dipf.de) to negotiate modalities and further procedures. It is generally helpful if you can provide the assessment instruments together with a collection of the standard documents (e.g. scales manual) and crucial information (e.g. study profile sheet) and the used scales for assessment.
I have noticed that DaQS indexes instruments I have developed myself. I do not agree to their being openly accessible. What can I do?
- In its capacity as the provider of the database for school quality, DIPF is highly interested in strict compliance with third party rights, i.e. the copyright holders (e.g. authors, publishing houses). Prior to recording any data in the database and according to our best knowledge, we have in all cases asked the copyright holders of the contents for their consent regarding indexing of assessment instruments and provision of open access. If, however, you have the impression that your rights have not been appropriately considered in this regard, please let us know so we can avoid conflicts. Contact
I have tried to transfer contents from the database but always receive an "error notification". Why? What does ODT actually mean?
- Contents of the database can be transferred in terms of the display of details of scales or studies, in text format. The OpenDocument Text is thus available. Respective files can be opened in MS Office Word (fron version 2007 onward without, older version with additional plugin) and Open Office.
