Taking part to the French effort around the photometric redshifts will materialize along two different lines :  \begin{itemize}  \item We are going to finalize our use of the local proprietary galaxy spectra obtained with the FORS2 instrument to critically reassess the use of interpolations based on 6 historical spectra, as was done in Gorecki et al. 2013. The key aspect of this effort, beyond the obvious pedagogical opportunity for some of us, is to investigate the possibility to separate better galaxy types and use this information prior to performing a template fitting. Beside the FORS2 spectra, we are also studying the SED atlas recently published REF. This work is lead by E. Giraud, and will proceed in close partnership with the LPSC and LAL LSST team. It is worth noting that we are also in contact with photo-z experts within the OCEVU labec perimeter, especially at IRAP.  Finally, a note is already been being  drafted, that will eventually summarize our study. \item We are taking part to the benchmarking of the homegrown LSST-France photo-z code, which is a hybrid template fitting algorithm with a final trained classification step to remove outliers. This code, developed at LPSC, needs to be compared to other mature software on identical real and simulated catalogs. The LAL team has recently obtained a matched spectro-photo catalogs of about 100000 galaxies that will serve as input. This activity will be collective in nature, with Johann Cohen-Tanugi intending to deploy and use at the CC the SkyNet toolSuite REF in order to compare to recent photo-z benchmarks REF; He is already in contact with Christopher Bonnett.  \end{itemize}
