The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a National Major Scientific Project undertaken by the Chinese Academy of Science. It is a unique instrument that combines a large aperture (4-m telescope) with a wide field of view (circular region with a diameter of 5 degrees on the sky) that is covered with 4000 optical fibers. It is the ideal tool to obtain low-resolution spectra (R~1800) for a large number of objects in a homogeneous and efficient way.

The LAMOST Extra-GAlactic Survey (LEGAS) and the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) were the two initial scientific driving forces for the LAMOST project. However, it was soon realized that the observation of the field-of-view of the nominal Kepler mission with LAMOST would be a pure scientific goldmine, being a win-win opportunity for both communities: it would provide the Kepler community with the data needed for a homogeneous spectroscopic determination of stellar parameters for objects observed by Kepler while the LAMOST community could benefit from high-precision results derived from data obtained elsewhere for Kepler objects to calibrate the LAMOST results. Therefore, the proposal of the LAMOST-Kepler project was well received in 2010 and the first observations for the project were already done during the test phase of LAMOST in early 2011.

The scientific observations of the Pilot survey began on October 24, 2011 while the Regular Survey started about one year later, on September 28, 2012. Now that the (first) Regular Survey is ending in June 2017 after the completion of 5 observation seasons, it is the ideal time to evaluate the importance of LAMOST as a large spectroscopic survey.

What is the current status of LAMOST and the LAMOST-Kepler project? What are the main scientific achievements in different fields based on LAMOST observations? What can we still expect from LAMOST in the future? The main goal of this workshop is to give answers to these questions based on the input from participants.
