The wide kinematical coverage of CLAS combined with a high beam polarization and high luminosity allows precision measurements of Lambda polarization. Significant effects were observed already at exclusive and semi-inclusive Lambda production at 5.5 GeV CLAS. The improvement of the accuracy of previous measurements of Lambda polarization allowing for decisive tests of models. Most of the particles in CLAS12 kinematical region are in the target fragmentation region.
