The fall kindergarten data collection took place from late August 2010 to late December 2010/early January 2011. The spring kindergarten data collection took place from late March 2011 to mid June 2011. Data were collected in about 970 schools across the country from about 18,300 kindergartners and their families, teachers, school administrators, and before- and after-school care providers.
The fall 2011 data collection took place from late August 2011 to late December 2011/early January 2012 in about one-third of the total sample of schools participating in the study. The spring 2012 data collection took place from late March 2012 to mid June 2012. In the spring, data were collected in all schools participating in the study.
The fall 2012 data collection took place from late August 2012 to late December 2012/early January 2013 in about one-third of the total sample of schools participating in the study. The spring 2013 data collection took place from late March 2013 to mid June 2013. In the spring, data were collected in all schools participating in the study.
Beginning with the 2013-14 school year, data collections will only be conducted in the spring. The spring 2014 data collection took place from March 2014 to July 2014. Data were collected in all schools participating in the study.
The spring 2015 data collection is taking place from March 2015 to July 2015. Data are being collected in all schools participating in the study.
The final data collection is planned for the spring of 2016, with data being collected from all participating schools.

Restricted-use and public-use files containing data from the kindergarten and first-grade rounds of data collection for the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011) are now available. Please note that while the ECLS-K:2011 was designed to allow for cross-cohort comparisons with the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K), the direct child cognitive assessment scores available on these files are not directly comparable to scores from the ECLS-K. Child assessment scores designed specifically for comparisons between the ECLS-K and ECLS-K:2011 cohorts are currently in development, with an anticipated release in the fall of 2015. It is appropriate to use data from the current data file release to compare the two cohorts in other ways, for example to look at differences in demographic characteristics or the home, school, and classroom experiences of the two groups.

The Distance Learning Dataset Training (DLDT) program at the National Center for Education Statistics (NCES) is releasing newly developed online training modules for several NCES complex survey datasets.
The DLDT computer-based training module resource is an online, interactive tool that allows users to learn about NCES data across the education spectrum and evaluate it for suitability for particular research purposes.
There are two types of NCES DLDT modules that are available: Common modules and survey-specific modules. The common modules help you understand NCES data across the education spectrum. They also discuss the methods NCES uses to ensure that the data, published products, and reports are consistent, reliable, complete, and accurate.
Lastly, the common modules help you understand how to access public- and restricted-use datasets.
The survey-specific modules provided in this training system present more detailed information about the specific studies conducted by NCES. Survey-specific modules are currently available for the following surveys: the Early Childhood Longitudinal Study Birth Cohort (ECLS-B); the Early Childhood Longitudinal Study Kindergarten Class of 1998-1999 (ECLS-K); the High School Longitudinal Study of 2009 (HSLS:09); the Progress in International Reading Literacy Study (PIRLS); the Trends in International Mathematics and Science Study (TIMSS); the Program for International Student Assessment (PISA); the National Postsecondary Student Aid Study (NPSAS); the Beginning Postsecondary Students Longitudinal Study (BPS), and the Baccalaureate and Beyond Longitudinal Study (B&B).

There are no in-person trainings currently planned for the ECLS studies.
